There are new players in the Middle East since Sykes and Picot drew up their agreement. Washington and Israel were latecomers, but eventually replaced both imperial powers as the major military forces in the region.
The enemy of the "Great Loot" was secular nationalism, and the U.S., France, and Britain have been trying to overthrow or isolate secular regimes in Iraq, Syria, Egypt and Libya since they first appeared. The rationale for the hostility is that secular regimes were run by dictators--many were--but questionably no worse than the Wahabi fanatics in Saudi Arabia, or the monsters the Gulf monarchies have nurtured in Syria and northern Iraq.
Why is Syria a dictatorship and Saudi Arabia is not? This past February, the Kingdom passed a law equating dissent, the exposure of corruption, or demands for reform with "terrorism," including "offending the nation's reputation or its position."
The list of names on the ledger of those who nurture terrorism in the Middle East is long. Yes, it certainly includes the Bush administration, which smashed up one of the most developed countries in the region, dismantled the Iraqi state, and stoked the division between Sunni and Shiites. But also the Clinton administration, whose brutal sanctions impoverished Iraq. And further back, during the First Gulf war, George H. Bush pounded southern Iraq with toxic depleted uranium, inflicting a massive cancer epidemic on places like Basra. It was Jimmy Carter and the CIA who backed Saddam Hussein's rise to power, because the Ba'athist dictator was particularly efficient at torturing and killing trade unionists and members of the Iraqi left.
Not to mention members of the Gulf Cooperation Council -- Kuwait, Saudi Arabia, Oman, the United Arab Emirates, Qatar, Bahrain, Morocco and Jordan -- who fund the Islamic insurgency in Syria. Some of those countries may decry the excesses of the Islamic State of Syria and the Levant (ISIL), but it was they who nursed the pinion that impelled the steel.
Turkish Prime Minister Recep Tayyip Erdogan is also on that list. It is through Turkey's borders that most fighters and supplies pass into Syria. So is the Obama administration, which farmed the insurgency out to Qatar and Saudi Arabia and is now horrified by the creatures that Wahabist feudal monarchies produced.
And don't forget T.E. Lawrence's French.
Paris has never forgiven the Syrians for tossing them out in 1961, nor for Damascus's role in the 1975-91 Lebanese civil war that dethroned the French-favored Christian minority who had dominated the country since its formation in 1941.
