I am thinking - in their logic, because an American Jew made a movie that insulted their religion, they are free to attack and murder ANY American.
Well, now that they've murdered an American, by their logic its the country of Libya's fault... so when will the bombs start dropping?
I've long feared the only way the Muslim World will show any sort of respect or restraint is if America show it's overwhelming strength and firepower. I understand disproportional responses aren't necessarily good, but I think that's what they need to do. You murder one of their diplomat? They destroy a neighborhood. You burn their flag, they burn your country.
Pick a nation, make an example out of them by bombing them into the stone age and this stops. Either that or send forces to seize the oil-rich region in Libya, fortify it and dare anyone to attack.
And every embassy they have should be on high alert with messages written on every wall in the native tongue - "We will shoot first and ask questions later"
