More evidence of the need for stricter control of the Mexican border:

PHOENIX A 39-year-old Iranian man has been arrested for allegedly trying to smuggle other Iranians into the United States through Mexico.

The U-S Attorney's Office in Phoenix says Zeayadali Malhamdary was arrested Thursday in the parking lot of a Mesa tailoring business he owns.

The F-B-I began investigating Malhamdary after a source told immigration officials that Malhamdary had sought help getting false Mexican visas so he could bring Iranians into Mexico.

Luckily, the plot was thwarted this time, and we cannot know whether the Iranians intended to engage in terrorism had they entered the United States. But what if next time the potential smuggler is not caught, illegals cross the Mexican border, and they detonate some kind of a weapon of mass destruction in one of America's cities?

If such an incident were to occur, tragically resulting in mass casualties, the political repercussions for the Bush administration would be almost incalculable, and I hope that fact is very much on the administration's mind as it contemplates the security of the Mexican border.
