besides spend it on frivolous shit like yachts and planes and stuff, there's no way it's all liquid. do they just park all their billions in a bunch of investment vehicles and wait for it to propagate itself? don't they get bored of just waiting and watching line go up?
Eh, international oligarchs do have diverging interests though. The Russian Bourgeoisie has Imperial aspirations and those are being thwarted by the American Imperialist machine. In their home country they have near absolute power but on the international stage they are the underdog that hopes to someday become the big dog.
True, but i think there is some level of "Honor among thieves" regarding what weapons you wield and don't wield. The same way nation-states generally don't use assassination against other heads of state, because ultimately it'd be really easy for the all the presidents and premiers and whatever to just kill each other and once that djinni is out of the bottle it's hard to put back.
Though actually now that I say taht I have doubts because the US and it's allies are pretty cavalier about just assassinating whoever they can...
