According to the Senate study, which adjective CANNOT be used to describe pre-war intelligence on Iraqi weapons?

President Bush has defended the decision to go to war in Iraq following a highly critical Senate study concluding that key pre-war U. S. intelligence judgments about Iraqi weapons capabilities were unsupported or overstated. The president also promised to work with Congress on reforming the nation’s intelligence agencies. The Senate Intelligence Committee report issued Friday accuses the intelligence community of treating ambiguous evidence as conclusive, ignoring contrary evidence and not challenging assumptions about Iraqi weapons.
