Russia was trying to turn Iran communist, so it spread the message that Britain was taking advantage of Iran's oil and stealing the country blind in order to help overthrow the government.
The Islamic revolutionaries and the communists helped overthrow the government.
Then the Islamic revolutionaries executed the communists after they complained that they weren't being given an opportunity to help administer the country.
The Islamic revolutionaries were basically chanting "neither east, nor west". No capitalism taking advantage of Iran's resources, no Russian communists taking control of their government.
From there, the revolution now had a state and it could leverage the state's resources to export and fund its revolution to other countries which it has done extensively.
The spark that caused the whole thing as far as I understand, is that Britain was taking advantage of Iran's oil which kept upsetting the population until they wanted something to be done. This probably gave communists an opportunity to come in, nationalize the oil and be the saviors, before then simply becoming the new oppressors of the population.
I don't think anybody was a hero, just Brits, Russians and the US strategizing around a country that seemed lost.
> it [the US] is the biggest organizer of violence, arms dealing, murder, corruption and every single one of your leaders has been a scourge inflicted on the world
These aren't independent events. Every time we impose our imperial will on other countries, the echoes winds up being worse, with a very, very limited number of exceptions.
> but can't win'em all.
We barely win any of them, but if your attention span is only a single generation, then I can see how you might fail to notice.
The US isn't an empire. Is Germany a US territory? Is Japan a US territory? Is Iraq? No. Is Panama? No. Puerto Rico and Hawaii are happily part of the US. We don't have to use military force or economic leverage to keep them part of the US. If the US government was destroyed, we would recreate it, because it is good.
The US also championed natural rights globally, which recognizes that people have rights that are not derived from any government, but are inherent. Guess which countries reject this? China, North Korea, Russia, Cuba, Vietnam, Saudi Arabia, Iran, Afghanistan, Syria and others.
> We barely win any of them
Winning depends on what you wanted to achieve. We don't need to win, we just need to get what we want. Our military won in Vietnam, but when conflict started again the government voted not to get involved. The Vietnamese love the US and hate China. South Koreans love the US. North Korea's leader loves the US and hates China. Japan loves the US and hates China. Saddam Hussein was killed in Iraq and we established forward bases to use against Iran. Afghanistan hates Iran. Osama bin Laden was killed. European countries and most Middle Eastern and most Asian countries are friendly with the US.
Everyone seems to recognize how Russia, Iran and China align. Our allies are getting stronger, because we're giving them tough love, while Cuba, Venezuela, Russia and Iran are all getting weaker.
You can interpret all of that however you'd like, but it doesn't sound like losing. People can delude themselves all they want and the media can yell from the top of the trees how everything is awful and we're losing and so on, but reality gets a vote. Don't let other people tell you what is real. Figure it out yourself and come to your own conclusions.
