We've got four star general - US Presidential candidate, and NATO Supreme Allied Commander right before 9/11 - Wesley Clark admitting it in public on YouTube. I'll never understand why the most important policy admission of the last 30 years is intentionally ignored in all discussion of what the West is doing in Iraq, Syria, Libya, et al. This is the Western powers - led by the US - looking to strip Russia's power out of the Middle East (or at least break it). According to Clark, particularly before China completes its rise to power (which would present a demand to dilute focus, weakening the ability to challenge Russia's strategic goals). These proxy conflicts haven't stopped for a single day since WW2. Don't take my word for it, or Clark's for that matter, just look at the powers in Syria wrestling over who gets to keep or acquire influence (the US/West v Russia).
