Why does the Dear Leader suddenly want approval from Congress to attack Syria?

Our Dear Leader was on a collision course this week to lob a few cruise missile at Syria for crossing the "redline" over the use of chemical weapons.  The latest shelling in Syria's continuing civil war appears to most experts, that they used the nerve gas Sarin to repel the rebels.

Our Dear Leader stated a while ago that Syria must not cross the red line as use chemical weapons on his own people.  With several reports that the latest shelling is the 3rd time Bashir Assad has used these weapons of mass destruction on his own people.  So this has "forced" the Dear Leader to react, less he losses what little international credibility he has left.

Many have speculated that he would order several cruise missile launched at a few "strategic" target and then boast, " I kept my word" and wag his finger at Assad and warn, "Don't to that again or I will get really mad and send bombers next time."

He also announced that he did not need the approval of Congress the act. This is in direct conflict with the opinion of Senator Obama as well as Presidential Candidate Obama.  Then Senator Joe Biden also stated that if the President unilaterally attacks a foreign country without the approval of Congress, it would be an impeachable offense.  So much for intellectual consistency.

But the International community, that Dear Leader assumed would back him, seems to have walked away.  Then our closest ally, Great Britain had a vote in Parliament not supporting Prime Minister Cameron's request for authorization to attack.  Whoops!!!

What to do?  If the UN, or a minimum of just a few allies, would back Dear Leader, he could claim "International Support" for his blatant act of war against the Assad Regime.

Sudden, he decides he needs the approval of Congress to attack.  So one has to ask why?  Has the Dear Leader called for an emergency session with Congress?  No.  Has he recalled Congress from their summer break? No!

So why?  It's simple.  It he gets the approval of Congress, if things go badly, he got congressional approval.  If he doesn't get approval, he can demagogue Congress for their lack of approval.

See, it's all about assigning blame for failure, insuring the Dear Leader is not responsible.

An often made statement about the Dear Leader's Leadership is, "Leading from Behind."  The correct description is, " Who can I blame, if it fails?"

P.S. 
Byron York at the Washington Examiner has a similar take on the situation.
