How 'bout, Psych!
The "consultation with Congress" clarification is proper, constitutionally correct, and good politics, too.
The "consultation with our allies" part is boilerplate, and probably good diplomacy. It won't make any difference if we decide something needs to be done.
The apparent backing-off from war talk is probably two things: first, it works to increase Iraqi confusion concerning our ultimate aims. Second, it impugns the NYT's "sources" for the "secret plans" they've been publishing. (I also suspect that the "immanent war" talk is mostly a case of media -- and DNC -- wishful thinking.)
