Charles Krauthammer is right on the money as usual; after all of President Bush’s tough words and promises, Iran is closer than ever to the ultimate weapon: The Advancing Iranian Nuclear Program.

WASHINGTON — On Tuesday, Iran announced it was installing 6,000 more centrifuges — they produce enriched uranium, the key ingredient of a nuclear weapon — in addition to the 3,000 already operating. The world yawned.

It is time to admit the truth: The Bush administration’s attempt to halt Iran’s nuclear program has failed. Utterly. The latest round of U.N. Security Council sanctions, which took a year to achieve, is comically weak. It represents the end of the sanctions road.

The president is going to hand over to his successor an Iran on the verge of going nuclear. This will deeply destabilize the Middle East, threaten the moderate Arabs with Iranian hegemony and leave Israel on hair-trigger alert.

This failure can, however, be mitigated. Since there will apparently be no disarming of Iran by pre-emption or by sanctions, we shall have to rely on deterrence to prevent the mullahs, some of whom are apocalyptic and messianic, from using nuclear weapons.
