Erm... yes, of course they would!
OK, so Iran doesn't exactly strike me as utopia and it seems generally agreed that nuclear weapons are kind of scarey whoever has them ...except if it's us and our mates when for some reason it suddenly becomes ok *confused look*
However, it does seem odd how surprised we always seem to be when the topic gets raised that all these other places might actually want them too.
OK, so from our position as big bullies of the world playground we may be able to turn around to all the littler countries and steal their dinner money to prevent them reaching us, but every now and then one of them will grow up and gain access to these things, at which point we suddenly declare them our mate and life carries on. We would never dream of giving up our power over the world though, why on earth would they want the same power as us?
Next thing you know we'll be finding one of these countries we don't like the look of invading them on fairly tenuous evidence and enforcing regime change to make them more like us... Oh, yes, hang on a minute, I remember now, we've already done that one
One day we may stop being hipocritical and actually get rid of our nuclear weapons like ElBaradei suggests. Who knows, maybe we'll even replace them with missiles made out of bacon.
In the meantime who's turn is it to polish the nuclear superpowers halo?
