No, we shouldn't. They've been cutting each others heads off for thousands of years.
That's the FSA cutting off that dudes head. In case you're an ignorant tool and don't know what the FSA is, it's the "Free Syria Army", whom is very closely allied with Al-Qaeda.
The FSA (Al-qaeda) want's the U.S. to get involved in their countries civil war.
I've seen damning evidence that the FSA is the one who used those chemical weapons in an effort to do a "False Flag" attack, drawing hte U.S. in to dammage the FSA's enemies (The Syrian Millitary).
This is THEIR civil war, not ours.
There's stupid people all over the world. Not just here...
Oh I know, it's just the fact that every-time we hear something stupid, it's from America mostly because of the fact that they are pretty much everyone's number one news source - Not sure if that made sense
