No non capitalist country can exist without being threatened and undermined by U.S. military and covert forces.
Evidence is needed for this claim. The countries that we were undermining were Soviet-bloc countries. Got an example of a non-capitalist, non-Soviet-bloc country that we were undermining?
When the leadership of these countries vow to create a fair social government they have little to work with except the rubble the colonizers have left when they are driven out. Zimbabwe is an example. They want to be fair to the people and the rest of the world still wants to dominate them. Those who are impatient and have no loyalty to their own country wander off to places like the U.S. and Europe, looking for a quick fix for their own personal sake.

Zimbabwe wasn't about being fair to the people. It was about taking everything in sight and giving it to his cronies. Only enough was distributed to the people to make it look like it was redistribution rather than theft. The redistributed land didn't work well, anyway--the people that got it didn't know how to farm (while they might have been working the land before they didn't see the big picture) nor have the money to plant and raise a crop.
Furthermore, he quit paying for maintenance. This was catastrophic. The problems were obvious immediately upon arrival--a big, nice airport with most of the lights burned out. Tons of luggage carts--which were useless because nobody had oiled the wheels.
