US foreign policy has been to attack the slightest manifestation of socialism anywhere on Earth but particularly in Latin America, “our backyard,” in other words, our colonial possessions. And indeed, official US policy is that all Latin American states are US colonies.
This goes back to the Monroe Doctrine, after which we stated that we will not allow any European (or other, as updated) country to interfere in Latin America. They’re our babies. We will fight to the death for them.
After 1900, with the rise of US economic power and formal US imperialism, which uses the US military and intelligence power to make sure US investors and corporations get the upper hand everywhere they wish to invest on the planet. In other words, the whole planet is a casino for the US rich and corporations.
And effectively that means that all nations under the boot of US imperialism (most countries, that is) are effectively colonies of the ruling class, the rich, and the corporations of the United States.
This effective colonialism is backed up by the might of the US military machine and increasingly, US economic power (control over international banking), which has now been weaponized to the point where the US Treasury Department is for all intents and purposes an arm of the Pentagon.
And indeed, US economic and military power work hand, with the first being utilized and at first and then the second utilized, if at all, only when the economic power seems to be fading as a coercive tool. But they definitely work together such that US economic and military power can be seen each one being a part of the other. It’s one entity. Call it the Deep State. The Deep State is simply “the foreign policy establishment of the United States. Its intelligence arm, the CIA is the head of the snake so to speak.
