You don't, but they do.
Iran’s threat is empty till they can act, and they simply cannot act in any meaningful way, ...
So you see no problem with allowing them to develop the means to act in a meaningful way.
Peddle your "stupid" somewhere else; I ain't buying.
The Nazi’s and Japanese and Italians thought they could rule the world, the Soviets thought that communism was the future of a prosperous society, Paul Pot thought he could rule Cambodia by killing, well everybody. The Roman’s thought there empire would last forever. England thought they could rule the waves forever.
If wishes were horse.
The Gods of the Copybook Headings with terror and slaughter return!
You presume to much, there simply is no evidence that Iran is close to building a Nuke, thier missile program is barly able to get off the ground, they buy most from russia, even as corrupt as russia is I doubt they would sell actual intercontinental missile tech to them, First gen nukes by a poor corupt dicatorship, would probable be the size of a house and unusable. It took us several years to shrink our weapons down small enough to fit on a missile, and billions of dollars, resources they simply don’t have, especialy if we drill, drill, and drill and got the price of oil down to $40 a barrel, thier economy fall over dead without $100 oil, as would most of our enemies, i.e. Saudi Arabia, Venezuela, Iraq, Iran, just to name a few.
Any dispute between Israel and Iran is thier buisness, while I would verbaly support Israel if they want to take action against Iran, all they should expect from us would be data and moral support.
