The conspiracy theory is that it was to keep poor people down
Which it was, however directly or indirectly.
The reality is that they didn't directly sell drugs
Yeah they did. Bought drugs too.
they just protected people who did to financially support terrorists
And right wing foreign governments, and right wing guerillas. And to combat left wing governments, and left wing guerillas.
it wasn't an attack on the poor
Yeah it was. A coordinated worldwide mission to oppress the left wing is a coordinated worldwide mission to prevent the poor from rising up and taking what's rightfully theirs from their rich oppressors.
