Leak Case Renews Questions on Rationale For War

- The legal and political stakes are of the highest order, but the investigation into the disclosure of a covert C.I.A. officer's identity is also just one skirmish in the continuing battle over the Bush administration's justification for the war in Iraq.

That fight has preoccupied the White House for more than three years, repeatedly threatening President Bush's credibility and political standing, and has now once again put the spotlight on Vice President Dick Cheney, who assumed a critical role in assembling and analyzing the evidence about Iraq's weapons programs.

The dispute over the rationale for the war has led to upheaval in the intelligence agencies, left Democrats divided about how aggressively to break with the White House over Iraq and exposed deep rifts within the administration and among Republicans. The combatants' intensity was underscored this week in a speech by Lawrence Wilkerson, the former chief of staff to Colin L. Powell while he was secretary of state.
