I could see this starting WW3. I think we all see it starting in the middle east. With all the major players backing smaller countries. Does China have a stake in all this?
I still would like to see us sit on the sideline unless the people are Syria are begging for our help. If they want us we'll be there, but are we really in danger if
we just sit on the sidelines?
I'd prefer we stay out of it as well. That raises another concern though. Why were the people in Kosovo and Libya more deserving of our help than the Syrians or the victimis in Africa? Consistancy please.
But I see any escalation being the result of being treaty bound to engage and not just choosing to.
As for China having a stake in this.
