Hezbollah out of Lebanon has infuriated Sunni's all across the Middle East. Many clerics are calling for a Jihad against the Shiite. In Lebanon alone this is turning into a civil war between the two sides. Let alone the fact that in Syria the Sunni's are wanting the Assad regime to fall.
Clerics are not going to let this aid continue without some sort of violence. We are looking at a regional conflict growing day by day. Each day new turns occur in this once Syrian Civil War.
