There is no evidence Iran is developing a nuclear weapon.
James Clapper, the director of national intelligence: "We don't believe they've actually made the decision to go ahead with a nuclear weapon."
"We do not know ... if Iran will eventually decide to build nuclear weapons."
Leon Panetta: "(Is Iran) trying to develop a nuclear weapon? No. But we know that they're trying to develop a nuclear capability. And that's what concerns us. And our redline to Iran is: Do not develop a nuclear weapon."
If Iran wanted a war with the U.S., it would be so easy to start one: just attack any of the plentiful U.S. targets in afghanistan, or fund an attack in america. There is no evidence they are doing any of these things. It is Israel--and perhaps the U.S.--sending their agents into Iran and assassinating Iranian scientists.
You'd think that after the Iraq fiasco people would realize that moving into countries on the basis of shaky intelligence is a bad goddamn idea. And if Iran actually is developing a nuclear weapon, this should be discouraged, but they have the freedom to do that.
Israel can defend itself with all the nukes it has yet still officially denies possession them and refuses to sign the non-proliferation treaty (which, btw, Iran has signed and still allows IAEA inspectors).
And if I were Iran, hearing bellicose language and under threat of sanctions from nuclear-armed Israel and nuclear-armed U.S., while bordering nuclear-armed Pakistan and rather close to nuclear-armed Russia and nuclear-armed China, all the while bordering the Saudis and their allies, who are begging to "cut off the head of the snake," I might be a bit encouraged to pursue a nuclear program (and yet there is still no solid evidence they are doing so.)
And how is the U.S. supposed to fund another (likely undeclared) war in the middle east? The country is broke, for christ's sake.
