"It's another utterly phony "false flag" propaganda exercise"

LH it appears to be that. The advantage that the U.S. has in getting involved on this issue is:
1. Obama can save face for his drawing the red line.
2. The Mid East is a powder keg and Obama wants to control this situation by police
tactics.
3. Obama ostensibly wants to show Assad that he can't use chemical weapons. The underlying fact is that the U.S. has used chemical weapons in the past, maybe not
sarin but others as lethal and only the U.S. is allowed to do that.
4. The U.S. has a pattern of supporting dictators when it suits its interest. FDR called
them "our bastards". The pattern concludes when dictators such as Hitler, Stalin, Osama, Hussein or Assad run afoul of reputed U.S. interests then for political, not moral reasons they decide to crack down militarily.
5. The munitions manufacturers are getting rich off of these wars and the taxpayer
is footing the bill. The advantage for them is self evident.
6. The Commander-in-Chief assumes undue power in times of war. Bush and Obama
have capitalized on this. They think it gives them a leg up in historical memory.
