There is ample recent evidence that the president has some difficulty with entrances and exits.  The linked video is a humorous example; the building conundrum in Libya is not.

President Obama’s decision to launch a series of military strikes against Libya raises a host of questions, many more than can be answered in his much-belated address to the American people tonight. At a minimum, the President must clarify the purpose and scope of the mission. He has declared that the sole object is to protect civilians from harm. Others in his administration, however, suggest that military operations will continue until Muammar Qaddafi leaves office.

In fact, the two goals might be contradictory, as the need to protect civilians from violence could well extend long after Qaddafi’s regime is toppled. If the rebels seize power and then turn their guns on former regime supporters, the U.S. military may find itself in the middle of a bloody civil war, as it did in Iraq. President Obama must provide assurances to the American people that he has not committed American blood, treasure, and prestige to a mission that does nothing to preserve U.S. national security, and might ultimately harm it.

Even if the President can clarify the mission, articulate an exit strategy, and give ironclad assurances that the U.S. military is not involved in yet another open-ended nation-building mission, the President’s speech this evening cannot explain away his blatant abuse of executive power. In 2007, Senator Obama declared “The President does not have power under the Constitution to unilaterally authorize a military attack in a situation that does not involve stopping an actual or imminent threat to the nation.” And yet no one has claimed that Qaddafi’s threats against the Libyan rebels posed a threat to the United States. Nor can anyone show that Qaddafi’s ouster would advance U.S. security. If the rebels prove more tolerant of al Qaeda or other violent extremists, the net effect of this intervention might be to increase the threat of attack against the United States.

Obama’s instincts in 2007 were correct. His ascendancy to the presidency appears to have prompted a change of heart, but no one should be encouraged by this Oval Office conversion. That his predecessors have similarly abused their power is no excuse. The United States is governed by laws, not by men. To allow a single person to wage war without the expressed consent of the people, as stipulated by the Constitution, merely compounds the serious harm done to our institutions of government over the past several decades.
