Little has changed about the US foreign aid budget in the last several years, despite your attempted pitch. The foreign aid budget has not been slashed, the US is still spending around ~1% of its budget on foreign aid, the same level it was spending under Obama.
Here are the foreign aid disbursement numbers by year:
2012: $46b, 2013: $46b, 2014: $41b, 2015: $48b, 2016: $47b, 2017: $45b, 2018: $46b, and 2019 disbursement figures are partial in the foreign aid explorer.
Mostly the US is failing to boost its foreign aid. Trump doesn't control the US budget (he has some limited influence) and there is a split power situation in the US Congress.
The US still provides approximately 1/2 of all global food aid, and has been doing that for a century. The US typically provides 300% more global food aid in a given year than all of Europe combined for example.
4% of the world's population, providing 50%+ of the world's food aid. Those selfish Americans, routinely saving the world from famines and hunger for a century and saving tens of millions (not a typo) of lives in the process.
"The United States is, by far, the world’s largest international food-aid donor. Almost every year since the 1950s, it has been responsible for more than 50 percent of the billions of tons of food shipped from the parts of the world with a surplus to the parts of the world that are hungry."
