You’re wildly out of touch if you actually believe if those dictators didn’t do everything with blessings from the US..
yemen is also 100 times worse off than ukraine its not even close
Look at what Iraq and Libya is right now. Libya has literal slaves right now, I'm sure US feels pretty good about themselves. Heck Obama won a noble peace price for it.
US supported Pakistan in 1971 when Pakistan was committing mass genocide in East Pakistan (Bangladesh now). They overthrew a government that people wanted in Iran because that govt. was going to nationalize oil and take it away from western oil companies. These things have been happening forever in the third world, but because it's brown people dying, people didn't care as much.
Anyways my enitre point is again, it's dumb to blame an average Russian person for the actions of Putin like how it would be equally dumb to blame american person for the actions of US govt. and military industrial complex.
Iraq? Evil dictator. Libya? Evil dictator. Syria? Gruesome terrorists/evil dictator.
Israel/Palestine? Messed up and the world still doesn't like it, but not on the same scale and certainly more complicated.
