Obama has now responded. While the US initially tried to cast Putin's move into Syria as a hopeful gesture of Russia aiding the Western Coalition forces in defeating ISIS, they are now strongly warning Putin to back down. Obama sent Kerry to call Russia and warn them last Saturday. Russia responded by saying they were bewildered the US would oppose Russia helping an ally they claim they have always and regularly helped.
Pressure is now increasing on Obama from US Allies to send military intervention into Syria now that Putin is making it clear he intends to help Assad. In fact as of today, Wednesday, 9/9, Intelligence reports that Russia has already sent in troops. The US responded earlier this week by asking Greece and Bulgaria to deny air space to Russia. Greece told the US no, Bulgaria said yes.
The problem for Obama is significant. In late summer of 2013, Obama was thwarted by Russia in attacking Assad in Syria. The rise of ISIS in 2014 gave Obama the pretext to send, at the very least, air power into Syria. Obama has wanted to topple Assad for sometime and his incursions against ISIS have allowed him to aid rebel groups in not only adding to the chaos in Syria, but weakening Assad. Russia can see that and is now moving to intervene. Putin will not allow Assad to go down. Obama is furious at Putin for moving so brazenly into Syria to assist Assad, international pressure is growing on Obama to do what he has always wanted to do -- topple Assad. But, the American people will not tolerate another war.
Without the American people's support, Obama can't move with massive military jabs into Syria.
Unless . . . the only way Obama could move into Syria as he has wanted to do for some time, as the allies are asking him to do, and as Russian's new moves are provoking him to do . . . is to somehow convince the American people he needs to attack Syria. How to convince the American people to go to war? A large scale attack on American soil blamed on Assad and the Syrians.
Could such a large scale false flag attack be in the works? It's hard to say. But short of something catastrophic happening on American soil that can be blamed on Syria, Obama won't have the political clout at home to move against Russia in Syria.
