Iran has weapons of mass destruction?

What do you think? War is business. First a big nation is selling his old stuff, next that big nation is starting a fight/war, 3rd step is sending food parcels and play the big saviour, last step: ignore the country as soon as you have what you want. There is no reason at all to fight wars anymore, so that is why there will always be war, it's big business. Who cares about Iran or their nuclear weapon? And if they have it why shouldn't they be allowed and other countries are?
