The US has always stood on the side of capitalist exploiters in Central America. The rougher the people have it, and the safer the profits are, the happier the US has been.
This has been the case since the early days of American imperialism, when we used our military to support fruit companies installing governments into Central American countries. That's why they were called "banana republics". (They were not even republics. They were more like virtual slave plantations.)
We were beyond "fixing stuff". The United States was helping to break stuff down there to make money in bananas, pineapple, and coffee. The businesses created a state capitalist government, creating extreme poverty, where the masses of people didn't own land, and were often dispossessed of their indigenous land.
The last incident was the Honduran constitutional crisis, when the left-leaning president Zelaya was pushing to revise the constitution. It was a leftward tilt revising a pro-business constitution. The military were undertaking a coup, the US knew about it, and didn't intervene to preserve the government.
After the coup, the government began attacking protesters. Opponents of the coup were beaten, killed, and tortured.
Have you read Smedley Butler at all? War is a Racket.
I've read some excerpts and some pages. I found a link to a copy so might read the whole thing soon. https://www.ratical.org/ratville/CAH/warisaracket.html#c1
Read it. Smedley Butler exposed the military-industrial complex and the corruption within US foreign policy the way John Taylor Gatto tore away the veneer of legitimacy from the education system. Both were decorated and renowned within the system, but stepped away to reveal the inside story when they could stomach it no longer.
