Why are we in Syria again? Take 2

[brimic]

I was doing some digging online the other night about the different factions involved in Syria, and the reasoning behind the conflict seems to be right out in the open. I don't know if I'm late to the table and this is common knowledge...

Synopsis- there is great want and need to build a pipeline from qatar, through Saudi Arabia, Syria, and into Turkey to supply Western Europe and Israel with Natural gas. Europe has been under the thumb of Russia for their NG supplies.
Syria is an ally with Russia, and Russia wants to build a competing pipeline from Iran through Syria, into Turkey.

Are we using ISIS  as a proxy to topple Assad just so NATO can get an easy supply of NG?
Everything seems to point in that direction:
We aren't helping the most effective fighters in the region (Kurds).
Turkey has recently been implicated in oil trades with ISIS.
Turkey shot down a Russian plane.
The only people taking an actual fight to ISIS despite all of the hot air blown around is Russia and Assad.

This wouldn't surprise me at all. 

Big business getting us into wars isn't all that new either.
