How did we get al-Zarqawi and his cohorts? Easy -- a little bit of inside information.

According to a Pentagon official, the Americans finally got one. The official, who spoke on condition of anonymity because details of the raid are classified, said that an Iraqi informant inside Al Qaeda in Mesopotamia provided the critical piece of intelligence about Mr. Rahman's meeting with Mr. Zarqawi. The source's identity was not clear — nor was it clear how that source was able to pinpoint Mr. Zarqawi's location without getting killed himself.

"We have a guy on the inside who led us directly to Zarqawi," the official said.

In a news release on Thursday morning, American military commanders hinted strongly that a member of Mr. Zarqawi's inner circle had pointed the way. "Tips and intelligence from Iraqi senior leaders from his network led forces to al-Zarqawi," the release said.

Iraqi officials confirmed that Mr. Zarqawi had indeed been sold out by one of his own.

"We have managed to infiltrate this organization," said Mowaffak al-Rubaie, Iraq's national security adviser. He declined to elaborate.

I guess that there is no honor among terrorists.

And that good intelligence beats good luck any day.
