Since the gloomy week he was elected president in 2008, observers – not critics – have been baffled by Swish Obama’s consistently oddball behavior.

The towering, frustratingly unanswered question looms:

Is his unorthodox behavior rooted in ignorance?

Or is it born of a willful desire to harm our country where he seldom has performed comfortably?

No thinker of stature has produced a satisfactory answer.

Never has there been a president who has openly, impudently slept with so many of our enemies, coddled them, while betraying his presumed fellow Americans with fairy tales about instantly converting lifetime bad guys into permanent, trustworthy good guys.

Throughout his two terms, Mr. Obama has treated the slaveholders of Communist governments as if they were harmless placeholders.

Operating seductively as if his main mission is to make life sweeter for our vilest enemies, Mr. Obama announced yesterday he was unilaterally lifting a 50-year ban on selling arms to the Communist government of Vietnam.

Why?

As if he were politically bipolar, the insecure Mr. Obama deliberately sounded a fresh but too familiar sour note yesterday.

At a news conference in Hanoi, the president grew his Odd Behavior list by one.

Historically,ending the Vietnam ban had been linked to a vast improvement in human rights. The Vietnamese state of freedom remains in rot, meaningless to our president who only favors liberating imprisoned black American criminals.

Earlier, Mr. Obama inexplicably made sweetheart deals with the toilet governments of Cuba, North Korea, Red China and his dearly most beloved the animals of Iran.

As if a small wave of fleeting guilt were washing over his vacation-craving body, Mr. Obama said the deal was not a carte blanche arrangement.

Arms sales would be evaluated on a case-by-case basis, he vowed. Simultaneously he reached for his wallet and purchased the Brooklyn Bridge.

By opening up a tasty economic channel for the business-starved Communist government of Vietnam, Mr. Obama obviates a need for war. We just surrendered.

As president, Mr. Obama said, he does not have to answer the question of why he engineered such a lousy deal – except that his desperation hunt for a legacy continues unabated.
