Why are republicans concerned about a nuclear Iran?

[Torie]

Iran has more of an "unhealthy" interest in Israel than Pakistan does - for starters. Iran is more of a nutter state than Pakistan. Pakistan already has a nuke so it's spilt milk, and Iran doesn't. Pakistan got the nuke because India did. Iran is not seeking a nuke because Israel has a nuke. Iran is not concerned that Israel will attack it - absent Israel feeling it is about to be attacked, or facing nuclear blackmail just as soon as Iran accomplishes its goal. Iran and Israel do not have contiguous borders, that are in dispute as to their existing lines.

Most Americans are concerned about a nuclear Iran, including in particular, President Obama, who has assured us it will never happen. The debate, and the partisan divide, to the extent there is one, is over the best strategy to accomplish that goal, within what is reasonably possible, not about the importance to just saying "no" to Iran, and preventing it, from acquiring this singularly effective weapon of mass destruction.

Hope this helps. It is almost a tragedy that this has become a partisan issue. It sucks really.
