Russia moving in under the pretense of ridding the region of ISIS is like the Mafia moving to your neighborhood under the pretense of eliminating street crime, then setting up a permanent base there to do Mob “business”.
Russia will grow wealthier, more powerful, more aggressive in their overall expansionist agenda (Eastern Europe, eventually elsewhere), and much more of a threat to the US and its allies throughout the world. Sure it’s great IF they actually do get rid of ISIS (we shall see). But having a country like Russia step in and gain such huge strategic advantage over the US is really nothing we should be cheering about.
If Obama was serious about wanting to take out ISIS, which I don’t believe he ever was—I think him and Putin are actually in cahoots on this whole thing despite his and Kerry’s moans and groans about it, it might not ever have come to this, although Russia would likely have come up with some other rationale or excuse for moving into Syria and taking control of it, and ultimately the entire Middle East.
The battle is really between Iran and Saudi Arabia. Russia is backing Iran and the USA is backing Saudi Arabia. The Saudis are using petrodollars to black main the USA into our military to help the Saudis take out an important Iranian ally, Syria.
The Saudis are far more trouble then they are worth. Our petrodollar deal with the Saudis will end sooner or later so why now end it now? The longer we wait the worse the effects will be.
