The thought of being remembered for something so bland and boring is weirdly scary to me. Maybe Felix was on to something when he talked about how settler-colonialism hollows out your soul and kills any culture, creativity or national identity you might've otherwise had.

You have to always push against Americans because even the most leftist Americans still hold some reactionary viewpoints somewhere inside.
I say this as the aforementioned "Euro-American" aka a white dude in the US.
Usually it's something to do with China, USSR, Iran, Islamic countries in general, or, recently, defense for Israel/kneejerk hatred towards Palestinians.
And as far as a more Marxist or material analysis of why Americans are the way we are (and I say we because none of us can escape all of this. We can try, but it's not possible to fully escape it. I cannot pretend that I am special or different and doing so would be pointless anyway):
Our material conditions in the US are objectively better than a lot of the world and certainly the global south which the US exploits in various ways. One of the more nefarious but never talked about, outside of niche leftist-type communities, is IMF loans and other financial tools of control.
Now, how do you explain to Americans who are relatively, within the US, poor but who are, in a global perspective, 'not bad off' that they should give a shred of a shit about atrocities committed by the US military? Well, to be super frank, you kinda can't. People have to change their entire fucking mindset and view of the world in order to see that the capitalists of our country collude with other capitalists and use financial and military strength to subjugate the world to enrich themselves.
Since Americans all collectively benefit to some degree from this exploitation, and everyone sort of knows this or can easily learn it, there's no material incentive to demand change to what we like to call euphemistically... "Foreign policy." "Muslims being tortured and murdered? Sounds bad, BUT what's his stance on healthcare for all Americans?" And just like that poof any chance at giving a shit has been dismissed without people even realizing that they've done so.
Try suggesting to about 80% or more Americans that the US military is OBJECTIVELY the most evil, murderous, terroristic force on earth and ever in world history and you'll get a SEA of "but China!" "The Nazis!" "The Soviets!!!"
Americans partly don't know, partly don't want to know, partly know and don't care, partly know and (my favorite) think it's good and benefits them either by making them "safer" (from whom? Who knows. The Russian-Chinese-Islamic terrorists or whatever) or in a material way. As if the US developing bombs and planes, wasting all those resources in the efforts, and then killing via sanctions or directly people abroad in order to extract resources really, actually benefits them. Not that it would be a justification anyway, but it's also just not really true. Most of the stolen wealth from other countries just goes straight to the top 1% or whatever of capitalists.
And as far as being a purely evil organization, the euphemistically-named (lots of euphemisms) US department of defense (when was the last defense done? Never. It wasn't even the DoD for WWII) along with the CIA, FBI, DEA, etc. as a fucking policy spent the last 80 or so years opposing actual democracies (socialist states) worldwide via terrorism, threat of annihilation, mass murders, rapes, hostage taking, leveling of all industrial centers, etc. to include literally everything a person can imagine. The US has sanctioned, approved, and done it all, including up until today.
I don't think Americans are beyond hope or whatever or that we (or Israelis) should all be killed. I know that's the meme and shit, but speaking for real, no. However, I will say, we (generally) cannot be trusted by the global south/third world to ever be good faith partners in peace or economic solidarity. Not as things currently are and likely will remain to be. I know that will hurt many Americans' feelings, but sometimes shit sucks and your country sucks so much fucking shit that you have a stink on you so bad that it can't be ignored. Americans tend to have this weird perspective that we by default get to be involved in everything. That we're the center of everything. Well, that's kinda true, but only for the evil shit mostly. Anything bad that has happened in the last century you can draw a fuckload of lines directly back to the US and good things like socialist projects worldwide are completely devoid of American influence. That's reason alone for me to say "clearly Americans need to just stay the fuuuuck away." And I don't think many people around the world are gonna be out there crying "no no let the Americans speak!" Another thing Americans don't know is that the world fucking hates us. Maybe not Americans, but definitely the US state.
The hardest but most important political stance any American MUST hold is basically: the US military and all of its adjacent and related entities (CIA, etc.) must be opposed from within, crippled as much as possible, ground to a halt, dismantled and destroyed.
That is the first and most important step to ending untold worldwide suffering which includes, ironically, inside the US. I don't like to spend much time dwelling on it, but martial states like the US (and Israel) suffer from that mindset at home too. We are mentally sick people. It's easy for us to judge Israelis since we are not Israeli (most of us anyway). But that's how the world also sees Americans! Maybe we're not so far gone down the specific little fascist rabbit hole that Israel went down, but we're every bit as islamophobic, racist, entitled, and just fucking annoying as Israelis. Of course the biggest obvious difference is Israel is a small country and limited by such in what it can do militarily. The US is very large and has no such limits. What Israel can and does do to Gaza and the West Bank the US can and has done to nations thousands of miles away.
Not much else to say. America is a fascist land of reactionary tendencies. If you're American and want that to end then you must oppose the US military and whatever that entails. You must purge from your mind of the idea of innocent US soldiers. If you find that hard to do, then just say nothing. It's better than screaming at those in oppressed nations (by the US military) how gross they are or whatever for celebrating deaths of US soldiers. You do not ever need to side with the imperialist or its dogs. The US military is fully voluntary. Everyone there chose, ultimately, to be there. People will argue whatever material reasons, but at the end of the day, the same as the IDF or the German Whermacht, a choice WAS made.
To your point, I joked the other day to a friend that a future president who doled out any kind of welfare state or god forbid land reform would be crowned king of America the next day and any following military action would see 99% support.
what does "not bad off" mean here? i'm absolutely miserable despite my privilege and the people who are "worse off" than me aren't killing themselves en masse, so you know, maybe trading relative poverty for absolute poverty and not living here would increase my quality of life?
Not really. It goes to everyone's who's a labor aristocrat or above, at least. You couldn't have a world where every person had the quality of life of a lot of Americans (including myself).
I don't know exactly what lifestyle you live or are thinking about, but there's absolutely no reason the entire world can't have all of their basic needs met and could do so with much less labor being done than now. It's not a resources limitation. The reason it seems otherwise, if it even does (I don't see it this way, but I think maybe I used to), is because we don't consider all the extreme inherent waste under capitalism. With a centrally planned, world wide distribution of resources and a common understanding of what we "need" there's nothing stopping humanity from everyone working a dignified amount of hours that leaves time for leisure but also having everything we need as far as shared, massive apartment complexes for living, community cafeterias where food is provided for everyone, and of course there's no reason "luxury" commodities can't exist either within reason.
Will the "upper crust" Americans see a reduction in their current QoL which essentially just translates to wasting a fuck load of resources? Sure. Probably. To me that sounds like a good thing though.
Regardless, the idea of convincing current day Americans to stop having this mindset that they HAVE to have a detached single family home or HAVE to have a personal vehicle or HAVE to be able to order Chinese fastfood, pizza, and ice cream to their detached family home at 3am seems impossible. Things will have to sort of "naturally" (climate change?) keep getting worse and worse and worse until people have no choice. And it'll take educated leaders at the right times and in the right places to force things in an equitable direction.
It's not inconceivable that this vision never comes to pass. People like their treats and are more than willing (we see day after day especially recently) to ignore or even cheer on suffering elsewhere if they get that treat. But just because it isn't happening and may never happen doesn't mean it's not possible. I just don't think that's true. I don't want to be reductive, but when I hear that type of argument my first thought is "maybe we're envisioning much different lifestyles" or "this person is advocating anarcho-primitivism!" That's sort of a joke, I think it's usually the former, but I do see some humorous "back to monkey" takes out there done in earnest.
Our posts basically agree.
Yes there will be a reduction in quality of life for basically every American labor aristocrat. There might be things to offset that like less mental stress of expenses like health insurance or taxes or whatever, or more efficient use of resources, but at the end of the day those people would have a lot less disposable income to spend on random stuff because being able to buy random stuff is not sustainable.
The idea that socialism is so much better and more efficient that it will magically solve most resource constraints and other issues the world has right now is the same kind of magical thinking where people assume technology like solar panels or electric cars are going to solve climate change. It's never that simple (I think we agree).
I would also extend this out to most of the Anglosphere, and I think some comrades would also extend it to most of Europe as well. We're injected with brainworms from the moment we're born in the west and it takes years, decades even, to fully deworm ourselves, Unconditional support for dunking on anglos who say dumb things here, this is the ideal place to get called out on it.
