How has the u. s. fostered both peace and conflict in the middle east ?

The correct answer to this open question is the following.

Throughout modern history, the United States has had many political and economic interests in the Middle East. With Great Britain, the US was one of the main promoters for Israel to settle in the Palestine territories, which, by the way, has caused tremendous conflicts since. The US has militarily invaded Afghanistan -for instance- when the Soviet Union invaded that Middle East countries in the 1980s. But years later -after the terrorist attacks of September 11- the US attacked Afghanistan.

Oil has been one of the main interests of the US in the region. When Iraq invaded Kuwait in the War of Gulf, the United States was the leader of the "Desert Storm" military operation to liberate Kuwait. But years later, in the George W. Bush administration, the US invaded Iraq saying that it had mass destruction weapons, and that was not true.
