Iran agrees to tough nuclear inspections

Two ways to deal with WMD proliferation. The first is to invade the offending nation, kill thousands, lose thousands (it's inevitable), waste hundreds of billions of dollars, bolster your terrorist enemies with new recruits, and watch yourself get dragged down into a quagmire with no end.

Or, you can use diplomacy, garner the engagement of the international community, and achieve the needed results with little cost.

Europeans and the UN took the latter approach with Iran, and surprise, surprise -- it worked.

Iran Saturday promised to give the International Atomic Energy Agency letters agreeing to tougher nuclear inspections and to suspend its uranium enrichment program, an IAEA official said.
