Right now they have the capabilities to start accomplishing their goals. They have money backing them, and they are calculated. They started off that way, remember ? They planned for months if not years piloting air craft before 9/11, and then hit 3 out of 4 targets. So they are no longer just talking, they are gaining ground, all that money the US spent in Iraq was for nothing. These people don't want democracy, they want their law under Iran leadership now that we've killed saddam. I think we should bring our troops home and stop interfering, focusing on our borders and our own security, not " world security " unattainable.Addressing title of OP: Haven't they been saying that for hundreds of years? (or words to that effect?)
