I think it's more fruitful to look at who benefits from the Ukrainian war.
Life for the average Ukrainian will not be radically different under Russian rule. Most of them will get up, go to work the same job they always have and funnel as much money as possible to those who already have it.
It just so happens that under Russian rule, Russian rulers will be making profit instead of Ukrainian rulers. The people actually fighting the wars never benefit and the ones who benefit never fight.

I don't want to have to boot from Debian installation media to install it on the USB drive.
