Petraeus points out the obvious:
The U.S. commander in Afghanistan on Monday criticized a Florida church’s plan to burn copies of the Quran on September 11, warning the demonstration “could cause significant problems” for American troops overseas.
“It could endanger troops and it could endanger the overall effort in Afghanistan,” Gen. David Petraeus said in a statement issued Monday.
The Taliban is already using the opposition to Park 51 for recruitment. I’ve no doubt they’d use pictures of burning Qurans for the same purposes.
