Persuasion
Very little in modern politics is new; 90% is older than Plato, and 10% is older than Babylon.
Obama's persuasive technique on his Syrian War is truly unique and truly unprecedented.
"Look, folks, I know yall have learned from our mistakes over the last 60 years. I know you're all sadder but wiser. Unfortunately, I'm not. I haven't learned anything, so you'll have to bear with me. You'll need to spend another trillion and send another few thousand of your sons to be killed, so I can learn this lesson which all of you have already learned. Consider it Presidential OJT."
I can only think of one other hypothesis, which is so far-fetched that it must be true. Obama is performing an 'installation' based on Heller's Catch-22. Breaking the fourth wall, as they say. Starting with the well-known fact that you have to be crazy to be President, he's demonstrating his craziness to the audience who are playing the part of the Re-enlistment Review Board in Heller's novel.
Or maybe he's just blindly obeying Israel's commands because he has no choice... Nah, couldn't be. That hypothesis is the simplest possible way to account for all facts, so it's impossible.
