There seems to be an inordinate amount of worry amongst many Americans in particular about the axis of evil getting nuclear weapons. Why? The US president has recently restarted research into the use of nuclear arms on what would previously be considered conventional targets, in particular as bunker-busters. So to the US government an increase in the use of nuclear arms is merely good policy, and certainly not something that has to be stopped.
Of course one could reply that Iran and North Korea are evil nations, full of monkey-men and maniacs hell-bent on reaping havoc throughout the civilised world. One would be an incredibly arrogant racist, but one could do so. After all, they do have turbans or slanty eyes; sure signs of the disreputable if encountered in any bastion of western influence, such as a mall or Jerry Springer. They must be practically champing at the bit to attack us.
One could also argue that Iran and North Korea has been at war with the west for decades. The recent occupation of Paris by Palestianian crack troops (hey, they're both Muslim countries/groups, right?) and the subjugation of Geneva by NK diplomats are cases in point of the two nation's recent history of constant assault on our interests and our peoples. Iran and NK also, like the treacherous French and those notoriously villianous New Zealanders also opposed our occupation of the third point in the axis: Iraq. If that's not an act of war, I don't know what is.
One could argue that Iran's anti-Israel rhetoric is merely a mask for their true hatred of non-Semite/Iranian peoples. Once they conquer the world's second most powerful military power they'll come for us next! It only stands to reason - Israel is practically the Constantinople of the modern world, providing the only entry-point to the western world. If it falls, there'll be nothing to protect New York or Washington from terrorist attack.
And of course we need only to look at NK and Iran to see two countries on their way to global domination. It's only through military invasion that we could possibly prevent their scientists from selling their expertise to the highest bidder in the same way the Iraqi scientists recently have. Waiting for them to fall would be futile, especially considering their domination in global economics and their robust social systems. Especially when we consider the instability that occurs around the end of a regime... you just don't get that instability when you invade. The current peacefulness and tranquility of Afghanistan proved that to the world.
Now that I think of it, there is a lot to worry about when two of the world's most insignificant middle powers gain nuclear arms. Perhaps the scare-mongers have a point...
