Not quite so simple. The United States has many different internal interests that disagree on many things between them, but align in spreading American influence globally through programs like this and many, many others.

However, it also has other factions, especially since Trump and his often bizarre, even irrational takes on what's important, basically took over the Republican Party, making a number of Republicans now also shun programs that previously, they wouldn't have so much as blinked at. This is cowardly of these people, but it's also par for the course with ideological shifts in political leadership.
