Lazs, that's just the thing - we haven't seen a mass exodus of terrorists (or maybe they slipped through out through our customs - which would be very scary) from the US. The Al Qaeda hijackers were in the states for several years.
The majority, if not all, of the terrorists over there in Iraq were in the middle east and Iraqies.
The number one terrorist threat to the US is Al Qaeda, and they're probably just sitting around in our own backyards plotting.
The battleground over there that was created for terrorists is just local terrorists that in many cases the war created.
If these weapons went into Syria and/or Iran, the world is not any safer.
