John Bolton, prophet

What the North has lacked thus far is the political opportunity to test without fatally jeopardizing its access to the six-party talks and the legitimacy they provide. Despite the State Department's seemingly unbreakable second-term hold over President Bush, another test after 2006 just might have ended the talks.

So far, the North faces no such threat from the Obama administration. Despite Pyongyang's aggression, Mr. Bosworth has reiterated that the U.S. is "committed to dialogue" and is "obviously interested in returning to a negotiating table as soon as we can." This is precisely what the North wants: America in a conciliatory mode, eager to bargain, just as Mr. Bush was after the 2006 test.

If the next nuclear explosion doesn't derail the six-party talks, Kim will rightly conclude that he faces no real danger of ever having to dismantle his weapons program. North Korea is a mysterious place, but there is no mystery about its foreign-policy tactics: They work. The real mystery is why our administrations -- Republican and Democratic -- haven't learned that their quasi-religious faith in the six-party talks is misplaced.

Negotiations like the six-party talks are a charade and reflect a continuing collapse of American resolve. U.S. acquiescence in a second North Korean nuclear test will likely mean that Tehran will adopt Pyongyang's successful strategy.

It's time for the Obama administration to finally put down Kim Jong Il's script. If not, we better get ready for Iran -- and others -- to go nuclear.

Today's real proliferation threat, however, is not Israel, but states like Iran and North Korea that become parties to the alphabet soup of arms control treaties and then violate them with abandon. Without robust American reactions to these violations - not apparent in administration thinking - more will follow.

Ahmadinejad on Monday rejected a Western proposal for it to "freeze" its nuclear work in return for no new sanctions and ruled out any talks with major powers on the issue.

The comments by the conservative president, who is seeking a second term in a June 12 election, are likely to further disappoint the U.S. administration of President Barack Obama, which is seeking to engage Iran diplomatically.

proposed a debate with Obama at the United Nations in New York "regarding the roots of world problems" but he made clear Tehran would not bow to pressure on the nuclear issue.

"Our talks (with major powers) will only be in the framework of cooperation for managing global issues and nothing else. We have clearly announced this," Ahmadinejad said.

"The nuclear issue is a finished issue for us," he told a news conference. "From now on we will continue our path in the framework of the (U.N. nuclear watchdog) agency."

The Senate, which must approve any treaty with a two-thirds supermajority, is now the only obstacle to Obama administration policies that will seriously weaken the United States. Voters should remind their representatives on Capitol Hill that they have a responsibility to keep us safe.
