I need to chime in.....
The murder of the American ambassador & three other State dept. officials will not bring about another war, for the simple fact that it had nothing to do with Libya, other than being the location where the act was committed. The murder was committed by a group of terrorists affiliated to Al-Quaeda. America is already at war against Al-Quaeda, so nothing changes there other than the fact they Americans will likely enter Libya in order to hunt down the murderous cowards. My guess is that they ran away like cowards usually do & might not even be in Libya anymore.
Second, the act was NOT committed because of that crappy movie. It was likely planned well-ahead of time, to coincide with the 9/11 anniversary. Protestors do not show up with machine guns, grenades & rocket launchers. What we're finding out is that the terrorists likely used the demonstrators as a diversion in order to infiltrate the area without getting detected. However, the compound itself was an easy target, considering no US marines were posted there & the doors had not been reinforced. All you needed to get in was a key.
And finally, there are many factors involved in higher gas prices. Among them are the recent hurricanes which just occurred in the southern US, the political instability in Iran & the middle east, etc. But i can almost guarantee you that a few hundred protesters in front of the US embassy in Cairo or the recent murder of American diplomats is NOT the reason why gas prices suddenly jumped up. Blame this on the oil speculators.
