Congressional calculus triggered Syria disclosures

WASHINGTON (Reuters) - If President George W. Bush wants to make progress on ending North Korea's nuclear ambitions before he leaves office next year, he first has to close the deal with Congress.

The White House took a step to try to win congressional support on Thursday by laying out intelligence alleging that North Korea helped Syria to build a nuclear reactor that U.S. officials say was destroyed by Israel on September 6.

The White House initially tried to keep the matter secret, fearing Damascus might be embarrassed by a public airing of the strike -- and the fact that Israeli jets apparently came and went unscathed -- and would be tempted to retaliate.

So it briefed only 22 U.S. lawmakers about the matter last year and it refused to comment even after The New York Times reported in mid-October that the Israeli strike had targeted a nuclear reactor.

Over time, the White House judged that the risk of Syrian retaliation against Israel, which is widely believed to have the Middle East's only nuclear arsenal, had receded.

Also, the administration has come under growing pressure from Congress to more widely share the information so that lawmakers will back, or at least not block, its efforts to end North Korea's nuclear programs.

Under an agreement reached in September 2005, the poor, communist state committed to abandon all nuclear weapons and programs in return for economic and diplomatic benefits.

The so-called six-party agreement was hammered out among the two Koreas, China, Japan, Russia and the United States.
