I hate a situation where doing the right thing is not in our best interest
I still believe that we should have rousing support from NATO at least. It is too much to hope that the UN would support the attack.
Our response if anything should be precision missiles or drones only. To lose one American life or the life of a Syrian innocent will make the response a disaster.
What ever we do, we should not do anything to affect the outcome of the Syria situation. Assad losing is not in our best interest imo. The rebels are shot through with extremist Muslims.
