Given those built-in obstacles, it has no need -- and can barely afford -- to invite needless trouble for itself, as it has with its inexplicably stubborn and short-sighted approach toward Congress on the Libya campaign.
Lawyers can argue, and evidently they did, about whether as a technical matter the Administration "had to" get Congressional approval for "hostilities" of this sort. But as a matter of politics in both the short-term and the broad historical sweep, of course the Administration absolutely had to involve the Congress. Short-term, by getting Congressional "buy-in" it would have buffered itself against the kind of rebuke it has now suffered. In the long historical view, it would have helped correct the drift toward unaccountable war-making power that candidate Obama himself was so eloquent in denouncing.
This was a problem foreseeable from the very start* -- more than three months ago, when we were told that this would be a campaign of "days, not weeks." Obama has so often proven himself to be the master of the long game that it is genuinely puzzling that he has stuck with this approach, rather than roping in Congress back in the days when most Republicans were criticizing him for taking too long to intervene.
Usually when his administration suffers a reverse, I blame the vicious nihilism of the opposition, or assume he has chosen the least bad of the dire options available. In this case, I cannot understand why he made and persists in what looks like a foolish mistake. Not the intervention itself, though I was skeptical of it. Rather, the refusal to engage Congress, which now leads to a predictable backlash.
* For the record, I'm not embarrassed to have what I wrote on the day this all began re-examined, in light of subsequent events. Also for the record, "own goal" is of course a soccer-world term for mistakenly knocking the ball past your own goalie and scoring a point for the other team.
One more for the record: a critical look at the other side of the Libya debate shortly.
