While our position is somewhat hypocritical and Iran has a good argument in favor of owning some, more nuclear armed nations is a very bad thing. As the amount of countries with nuclear weapons increases the likelihood of an nuclear accident or warfare too increases. While you can attack the U.S. and allies for hypocrisy, you have to admit they are on the right side of the debate. A nuclear Iran is not a good thing for anyone on the planet.
Also it is wise to have a bit of perspective when talking about U.S. hypocrisy in this case. All of the nuclear powers, especially the other big two (China, Russia), will do everything in their power to make sure a neighbor doesn't get nuclear weapons. Russia would case a shitstorm is Poland was building some. China would flip the fuck out if Vietnam was building some. The international system is chaotic and self interested. Nothing new or American specific here.
