In fact, this current civil war in Syria is actually helping the U.S. Among other things, it's distracting Iran and Syria with their proxy war there. It's sucking all the energy of the Middle East into Syria.
I do, however, doubt Buchanan's claims that President Obama is such a hero in that regard. First of all, the President may get us into that war soon. Secondly, how come Buchanan gives him a pass on Libya? We had no reason to invade Libya. We only aided Al Qaeda by doing it. We were giving money to Gadaffi immediately before that.
It seems like Buchanan isn't always for putting the U.S. first and staying out of local wars first. He's quite the neocon when it suits his purpose. Maybe people should call him miniMcCain.
You have to find another source for info. Buchanan was against the war in Libya.
