Should we say that every other country that doesn't provide aid equivalent to what USAID did, is also killing those 14 million? E.g. China, Japan, India, Brazil, the UK, Saudi Arabia, France, Russia, Canada, Mexico..?
Many countries have their variation of the USAID. In fact the UK, France, Canada, etc. have such programs.
I'd argue that these are an investment in the future and end up being positive for the countries investing in them, in the form of the world being a better place, putting less pressure on immigration flows, and so on.
Per capita, other countries contribute more, so this wasn't such a wasteful use of American resources.
And absence of such a program elsewhere doesn't take away from Musk's DOGE wilfully destroying the program. Yes, that's in his legacy, the deaths that will be caused.
No matter what his companies builds or accomplishes, those numbers are his legacy.
