Let's hope not. But it is kind of concerning now that more evidence is accumulating that Syria used chemical weapons against the rebels there. And if we can help people in Libya overthrow Qaddafi why can't we help people in Syria overthrow Assad?
I really like the idea of people taking back their country from an authoritarian regime. People deserve to have some say over the kind of government they have, even if they choose one that we don't like that much (Muslim Brotherhood, for example). If we really stand for democracy, how can we think people will believe us if it's only governments that give us what we want (Exxon, BP, etc). Let's take a risk and let people see for themselves if choosing an Islamic group is a bad choice. As long as the people can still vote them out of office, we should take that risk.
