Iran vs. Israel: What will the U.S. do?

    In an article by Nicholas Kristof he talks about Iran. Iran is a very powerful country, not in the sense of overwhelming armies and power, but in it's effect on the rest of the world. Iran is famous for it's oil and nuclear, not always in a good way, and we are somewhat in their mercy for these resources. Many countries buy oil from Iran, including the United States. Oil prices would skyrocket if we were to upset Iran and end trade with them. The problem is Israel... The U.S. pledged themselves to the country of Israel after creating a stable government to them. Israel contains mostly Jewish people and they are constantly fighting against the many Muslim countries that border them. Israel and Iran have both hated each other after Iran's leader in 1979 said Israel wasn't even a country. Over the years tension has been very high and threats of war are lurking. If a war starts between Iran and Israel start, what will the U.S. do?
    The U.S. has always been the World Police for over a century. From helping overthrow an unfair dictator, to lending support for the survivors of a natural disaster. But has the U.S. gotten itself tangled up too far. Iran is possibly developing nuclear weapons and Israel may launch attacks on Iran. Will this pull the U.S. into war? Will this set off a chain reaction? This conflict may lose us a very important trade partner, which is important when you deal with oil. The U.S. has already put limiting sanctions on Iran and is about to be pulled into this maelstrom.
    In conclusion the U.S. has really tangled themselves up. This situation can affect us economy-wise and military-wise. We have to get out of this mosh-pit. The only problem is that we've gone too far to just go back, which is what happens in most of our conflicts.
