Aaron Worthing at Patterico's Pontifications ("Harangues that Just Make Sense") is reading the plain English meaning of the War Powers Act.
Money quote(s):
"If you are going to argue that the President can do this under his inherent powers under the Constitution, that is fine. I will disagree with you, but you are within the realm of reasoned debate. But you can’t pretend that the War Powers Act covers this—you can argue that this power is inherent in the office of Commander-in-Chief, but you can’t honestly and competently claim that the War Powers Act covers this. This isn’t a foreign language. Hell, this isn’t even lawyer-code-talk. We were not in an emergency created by an attack on the United States, its territories or its armed forces when Obama started bombing Libya. It is, simply put, a lie to say it lawful under this act."
As I've noted before, as over-lawyered as our military leadership structure has become, this has to have been staffed so that the various generals and admirals don't have legal exposure on this.
"(D)uring the Revolution our military force was pretty pitiful, too, but usually the underdog loses. That is why we call them the underdog, and why it is an inspiring movie cliché when they win. Because they usually don’t win. So we might end up blowing another hole in our deficit, with little to show for it.
Nice. I have supported the idea of intervening from the beginning. I think McCain was right to ask for intervention when he asked for it. But if in our dithering the rebels have dwindled down to a force that cannot win, then we have to fish or cut bait. We either do a full scale invasion—which I oppose—or we shouldn’t even bother.
But just having a no-fly zone (which apparently does include blowing up some tanks—huh?), is just half-assed."
This is called limited warfare. Which is kind of an elastic term, as it's defined more by what it's not (it's not unlimited warfare, in other words).
"I had been trying to put words to my concern about how this war has been run for days, and I think I finally found the best metaphor. It’s the Underpants Gnomes theory of warfare. Of course I explain the Underpants Gnome metaphor here, but this is Obama’s theory of how to win the war:
Step 1: Enforce a No-Fly Zone Step 2: ? Step 3: Regime Change!
So his second step is a question mark, because he is just hoping the Rebels do something to take down Qdaffy, but he has no idea what it would be, or apparently even if they are capable of doing it, with our help. I support regime change and so on, but I am against half-assing it.
Anyway, Congress has to put its foot down. At the very least he has to be censured. That should be step one. And if Obama continues to show this contempt of the separation of powers enshrined in our Constitution, it would be impeachment time. And some would say it was overdue."
Congress doesn't seem to be having many problems with this thus far, aside from one or two Members raising the issue.
If U.S. involvement escalates (think "boots on the ground") or we start to take losses of men and materiel, and it could become katie-bar-the-door time in D.C.
