"Once that's true. I am pretty sure they don't even have to go to war with Ukraine."If Russia has half as much money as the US to put in their military, it would mean that their economy is at least 5 to 8 times that of today. Once that's true. I am pretty sure they don't even have to go to war with Ukraine. They would have enough economic cake to make Russia-Ukraine strategic relation profitable enough for Ukraine that Ukraine won't stay so poor. Once both Ukraine and Russia are both rich and have very good growth, the Ukrainians won't be so desperate to join EU, and Russians won't really be as intimated by the EU as they have been.
You act as though Russia's invading Ukraine was supposed to be good for Russia's economy.
While I doubt that Russia's economy will collapse completely (as many Westerners hope), it should be
clear that Russia's economy will suffer for the foreseeable future.
I would add that Russia does not have enough money to bribe most Ukrainians into pretending they are really Russians.
