Perhaps it is true that Obama wants the support of Congress in order to take military action against Syria. Perhaps. I think something else is playing out that in part has influenced his decision to delay action.
I believe that President Obama is planning and coordinating the military action until he gets all his ducks lined up for the attack. He is preparing the revolutionary forces in Syria, at least those who come somewhat close to being democratically motivated. I think they will take direct action when the bombing and missiles begin attacking Syria. Coordination for maximum effect is important and necessary.
Also, I believe Obama is working to coordinate other nations to take part in the attack. Who might that be? France seems ready to join us in our action, and their involvement is being coordinated. At least some of the Arab states will be involved, to varying degrees. The Gulf emirates, for example. Saudi Arabia might play a silent role and provide financial support. And Israel will be on careful alert because they could receive a counterattack from Syria or even from Iran.
What role will Turkey play? They have been very inconvenienced and angered by the role Syria has been playing during that civil war. Turkey could be pivotal.
All this international preparation and coordination is necessary because of the great danger of a much larger war erupting after the U.S. attack.
The horrible action by the George W. Bush administration in Iraq and Afghanistan, coupled with torture and Gitmo, has left the U.S. vulnerable to great distrust among the world's nations. The President of the United States will be burdened with these mistakes for many years. Obama is burdened by them today.
There is a complex amalgam of thought and opinion in the U.S. about foreign actions. As with Iraq, the foreign policy "experts" in the American bureaucracy are poorly informed about history in the Middle East and act out as though European standards hold true there. Ridiculous. The educated university community is a dichotomy to bureaucratic stupidity. University professors, seated in the unreal environment of a university campus, offer silly opinions from their very "distant" locales.
Faced with this complex spider web it is close to impossible for President Obama to make the right decisions. But decide he must. He has my sympathy and my empathy. Support our President.
