Iran
Just leave them alone. There is no "Iranian problem". They are a threat to no one. Iran hasn't invaded any other country in centuries. No, President Ahmadinejad did not threaten Israel with any violence. Stop patrolling the waters surrounding Iran with American warships. Stop halting Iranian ships to check for arms shipments to Hamas. (That's generally regarded as an act of war.) Stop using Iranian dissident groups to carry out terrorist attacks inside Iran. Stop kidnaping Iranian diplomats. Stop the continual spying and recruiting within Iran. And yet, with all that, you can still bring yourself to say: "If countries like Iran are willing to unclench their fist, they will find an extended hand from us."2
Iran has as much right to arm Hamas as the US has to arm Israel. And there is no international law that says that the United States, the UK, Russia, China, Israel, France, Pakistan, and India are entitled to nuclear weapons, but Iran is not. Iran has every reason to feel threatened. Will you continue to provide nuclear technology to India, which has not signed the nuclear Non-Proliferation Treaty, while threatening Iran, an NPT signatory, with sanctions and warfare?
