@hmmmmmm When major natural disasters happen the US often lends a hand or money.
On my recent Q about whether photos sway people regarding the conditions at our detention centers a jelly pointed out we pulled some of the money and aid we had been giving to Guatemala and Nicaragua, which means at least for some amount of time we have been helping.
The US government gives money to the Gates Organization, which has efforts going on to eradicate Polio in the world, and also giving other vaccines.
We gave money to help fight HIV and AIDS in Africa, I don’t know if we still to it.
Here’s a Wikipedia link about foreign aid. Granted some of the efforts have motives to help our own country, but it still is also in the interest of helping others. https://en.m.wikipedia.org/wiki/United_States_foreign_aid
Also, after WWII we helped Germany and Japan rebuild. They didn’t like our presence in their countries, but just look at West Germany vs. East Germany when the wall was up. We allowed the countries to flourish. Germany had been a democracy, a capitalistic country, with high levels of education, and with America in the West it was able to go back to the path it never should have veered from. With Russia in the East, it was controlled and kept down with communism.
I’m not discounting some of the crap we have done, remember I agreed the US can be a bully. I often pout out we are the only country in the world to actually drop nuclear bombs. Then we have the gall to say other countries can’t have them.
