@georgeob1,
While the US will be threatened by a Nuclear Iran, in that Iran is the #1 terrorist nation in the world, the most significant threat is to Israel.
Now, since Obama tells us that his Administration is more pro-Israel than any other in history, one would think that he takes this threat very seriously.
Bibi doesn''t think so, but who the hell is he? Just a wild-eyed Likud facist who favors Romney; not the person with ultimate responsibility for the security of his nation and the safety of his people.
But put aside Iran actually ever using their nukes. They're having them changes the geo-political dynamics of the region immeasurably.
Look at what they are doing to establish hegemony over the region without nukes and imagine how much more successful their efforts will be with them.
If they get them, does anyone think that Saudi Arabia with it's trillions in petro-dollars will not make every effort to follow suit?
The Left loves to wail about nuclear proliferation, but their only answer to the problem seems to be US disarmament.
The more second rate nations that have nukes the greater the probability that they will be used.
Should there be a detonation of a nuclear bomb in the next ten years, probability greatly favors that it will be one produced by Pakistan, North Korea and (if we allow them to get them) Iran.
We've already seen how one brilliant fanatic (Abdul Qadeer Khan) can spread the nuclear wealth. Is it so hard to imagine that once nations like Iran have nukes, nations like Venezuala might obtain them?
