so your idea is to allow every country to have nuclear warheads since we do? really? thats your idea of a peaceful world? sure, lets just give them to every crazy dictator...i mean whats the worst that could happen, right? iran doesnt have a horrible track record of killing their own people or anything...surely their great respect for the life of their own citizens would be extended to the rest of the world.
but lets break down your logic here...
you say that iran would never use it because they know if they did that they would get wiped out. then you say you support them getting it for 'deterrent purposes' which can only mean that they would use them as a way to not get attacked---i.e. they would use them to prevent being attacked.
so which is it? either they would use them as a way to prevent being attacked or they wouldnt use them at all. and if the answer is that they would use them defensively, then why the @!#$ would we want to give them the opportunity to use them at all? but if the answer is that they wouldnt use them at all, then what is the point of them having them?
the world is safer the less countries have this power--especially crazy, power hungry countries that suffer from the little man syndrome
