Iran and Syria have control of very powerful terrorist organizations and if nothing is done about them they will use them against us. If Iran gains nuclear weapons they will use them either in the region or give them to Hezbollha(sp) to use around the world. If you doubt this possiblitiy then you are just burying your heads in the sand and hoping it doesn't happen instead of stopping it from happening. When Iran produces enough enriched uranium we will see dirty bombs used everywhere.
