Atheos, those missiles do not have a nuclear warhead. As such, they are not going to obliterate New York, London or Jerusalem any time soon. Even if they did have a nuclear warhead, ever wonder why India, Pakistan, China, or Israel haven't ever used nuclear weapons? They are a deterrent. The only time nuclear weapons have been used was when there was one single power with access to them.
I live in a country that was speaking Russian in the 50s. Despite living in an area that still bears the scars of a brutal occupation, I am glad the Cold War never heated up, and that sane heads prevailed on both sides in the various crises during the Cold War, because that means my country still exists. You probably would have launched nukes during the Cuban Missile Crisis, wouldn't you? That would have turned out just great, except for all the dead people from blasts on both sides, along with the lasting effects of nuclear fallout making our planet an unlivable hellscape.
I don't want to trade security for profit, but am aware that that is all the US government is charged with caring about these days. Personally, I am glad that the Iranian people finally have access to goods that they desperately needed.
