The way I see it, the longer this war goes on, the weaker Russia gets. Sure it's costing the US (and other countries) a lot of money and resources but we are essentially weakining a not-so-friendly country of ours without having to send our own troops to fight it.

I'm really skeptical of the "we're grinding Russia down with this!" narrative because the USSR had been cranking out war materiel to compete with the USA for literal decades; the RF has been working around Western sanctions for years and IIRC have been really focused recently on economic self-sufficiency in a few spheres.

They're also the country with the most tanks in their fleet (total, not necessarily deployed), and they have air superiority, which Ukraine can't really challenge.

Honestly it looks like Ukraine will lose, but not before defense contractors get to sign contracts worth billions of dollars replenishing the West's armories.

Also by itself Ukraine's government isn't worth supporting, they've rolled back labor rights, allow the existence of fascist military units (Azov Battalion is part of Ukraine's version of a Gendarmerie - a military unit that polices civilians), and they're corrupt as fuck, they're privatizing aggressively during wartime.
