Was this you answering my questions? If not having a degree isn't bad, why don't you just say it?

I am a psychologist. Psychology is mostly irrelevant to having a place in international relations. Unless you are an industrial organizational psychologist, which may land you a job in some kind of government job such as dealing with army recruits or other international jobs in the private sector. I don't see the need for anyone to bring up their degree in an Internet debate. For one, it's irrelevant. Two, it's impossible to determine truthfulness. And appeals to authority in the self leads many to believe that they don't need to prove their point, hence that Hobbs guy saying along the lines, "you don't have a degree in international relations therefore I am right and you're wrong." This is fallacious.

You think the US is attempting to monopolize all oil? Seriously?

This is obvious from US foreign policy from the 1950s onward. The majority of the oil is in Saudi Arabia, the other gulf states, Iran, Venezuela, Russia, Canada, and the United States itself. We have deals with Saudi Arabia and the other gulf states to get oil at a very cheap rate from them. Notice when the Yemeni population just now tried to have a regime change from the former pro-West monarchy to the anti-West Houthi, immediately Saudi Arabia starts a bombing campaign with US weapons. We sell them more weapons. It is apparent that the Saudi bombing campaign is sanctioned by the US. When Iran in the 1950s elected a head of government that promised nationalization of the oil industry, (in other words removing the oil rights of Iranian oil from BP and giving it to the Iranian people) we staged a coup against his government in 1953, placing a dictator, the Shah, in control. When Iran rebelled against having a western puppet in control in 1979, they became our enemies effectively resulting in the United States losing control of Iranian oil again. So from then until now Iran is declared an enemy of the United States. Iraq became a friend under Saddam because he was an enemy of Iran, and America also liked buying cheap oil from Saddam. It wasn't until Saddam invaded Kuwait, another oil nation, that the US decided that he wasn't a friend anymore. When Chavez decided to nationalize Venezuelan oil, the United States decided to enact many embargoes on Venezuela. The Russian Oil industry is constantly hit with western economic warfare by the west and OPEC allies. Remember last year or so when oil went down to like a dollar per gallon. That was the result of Saudi Arabia lowering prices of oil to undercut any profits that Russia could make from selling their oil, to destroy their economy even more in addition to the sanctions from the Ukraine conflict. All this adds up to yeah, I definitely think that the US is trying to monopolize on the oil of the world. Especially considering the fact that wars result when a country decides they are not going to do business with the United States. This is obvious imperialism.

Democratic regime change can happen, though I will admit that it is not very common. If the people elect to have a government radically different from the former one, then it is a democratic regime change.
