"MATTHEWS: I put the question to you, you`re president of the United States and an enemy is beheading one of your people every couple of weeks. What do you do? Can you do nothing? Can you sit and watch it happening? This open-ended barbarism against your people? But what if the one thing you can do to stop the beheadings is invade Syria and begin taking control of the country, city by city, village by village?" (thanks Basim)
