Does Congress have a say in a "war" it never declared?

Consider the remarks of John McCain:

"We feel very strongly that it needs to be condition- based, because if you tell the enemy when you are leaving, then obviously it has an adverse effect on your ability to succeed. So that is a major concern. And there's still a great deal of ambiguity about that issue."

...During yesterday's press conference, Sens. Lindsey Graham (R-S.C.) and Joe Lieberman (I-Conn.) backed up McCain's assertions.

But let's consider this: Since 1945, Congress has failed to declare war on anyone or anything. Instead, they have left all war-making authority to the President. Why? You tell me. Mostly political cowardice, I'd wager.

So it's easy for these old wise men to kibbitz and criticize, but if they want to set conditions on the war — and especially since they aren't trying to stop an undeclared war — maybe they should get Congress to declare the fucking thing and then they can review to their hearts' content.

Until then, it's all posturing. Right or wrong, it's posturing.
