Gas prices have been going up since the first recent rebellion in Tunisia, then Egypt, and now Libya.. along with civil turbulence in a handful of other countries that has the oil speculators saying that they're "unsure" of the availability of oil in the near future (There was even a wave or two in Saudi Arabia that made some people uncomfortable/sweat a little and that did a bunch to help give them reason to start jacking up).
There's a pretty sizable oil port in Libya that's completely shut down and at 0% output, with all of their storage tanks full to capacity.
..On the subject of the US and other countries being involved.. I definitely like the fact that the US (my country) has been keeping out (atleast on the main stage) of these events... sure the officials are making public statements and such, but I mean as far as not becoming militarily involved or making direct threats.
However, someone likened this situation to that of Iraq, and I feel that wasnt quite appropriate. The reason people got mad about Iraq was because the United States went into that country against the will of the UN. There were lots of major nations opposed to us doing that. While in this situation, the UN is considering action of it's own, so if the US does get involved somehow, it will probably be accompanied by other UN nations and the support of the international community.
I do see some reflections of Iraq in this situation though, because I believe that what has happened in Iraq helped to set off these events. After decades of dictatorship, the Iraqi people are having open elections... all these other countries living under dictators saw that, and began to think... if they can do it, why cant we?
So people living under these brutal rules got angry and started to ask questions out loud and make demands, and when the government attempted to put them down, more people got angry.. and it grew, first in Tunisia... then the Egyptians saw Tunisia and asked "Why not us?"... then Libya followed suit.
