US government is simply more civilized and predictable.
Of course, that's just development aid. US blows away all other countries in humanitarian aid too: https://www.statista.com/statistics/275597/largers-donor-cou...
The problem is that they often do blow stuff away, quite literally. People aren't going to sing your praise for the new well you've dug after you've bombed their wedding and killed all their friends and family.
If you want to do some good, take some refugees. Like, a significant number, not a homeopathic amount.
Is that the only reason you do not think they are civilized? Any countries that have dropped bombs are not civilized?
195 countries in the world... Only have to find ~100 countries that have bombed another country in the last century. Only thing I can see that is going to save that assumption is going to be ww2.
