also didn’t the CIA fund the terrorism?

From Operation Gladio by Paul L. Williams (p. 271):

“During the Cold War, a Pan-Turkish movement was unleashed by Col. Alparslan Türkeş, the Gladio commander in Turkey, who upheld a belief in Turkish racial superiority. He envisioned the restoration of the Ottoman Empire from the collapse of the Soviet Union, which kept the Turkish peoples of Central Asia in political and economic bondage. The Grey Wolves, the ‘youth military unit’ formed by Türkeş, were named after the legendary wolves that led the scattered Turkish tribes out of Asia to their homeland in Anatolia. This task did not seem daunting. Thanks to Gladio, the CIA had controlled Turkish affairs for decades. Çatlı, as a disciple of Türkeş, was an extremely useful agent provocateur—an operative capable [of] expanding both the drug trade and the strategy of tension within Xinjiang and Central Asia. Throughout the 1990s, hundreds of Uyghurs were transported to Afghanistan by the CIA for training in guerrilla warfare by the mujahideen. When they returned to Xinjiang, they formed the East Turkistan Islamic Movement and came under Çatlı‘s expert direction. Graham Fuller, CIA superspy, offered this explanation for radicalizing the Chinese Muslims:

The policy of guiding the evolution of Islam and of helping them [Muslims] against our adversaries worked marvelously well in Afghanistan against the Red Army. The same doctrines can still be used to destabilize what remains of Russian power, and especially to counter the Chinese influence in Central Asia

This policy of destabilization was devised by Bernard Lewis, an Oxford University specialist on Islamic studies, who called for the creation of an ‘Arc of Crisis’ around the southern borders of the Soviet Union by empowering Muslim radicals to rebel against their Communist overlords” (Williams 240).

“…without the Cold War excuse our foreign policymakers had a real hard time justifying our joint operations and terrorism schemes in the resource-rich ex Soviet states with these same groups, so they made sure they kept their policies unwritten and unspoken, and considering their grip on the mainstream media, largely unreported. Now what would your response be if I were to say on the record, and, if required, under oath: ‘Between 1996 and 2002, we, the United States, planned, financed, and helped execute every major terrorist incident by Chechen rebels (and the Mujahideen) against Russia. Between 1996 and 2002, we, the United States, planned, financed, and helped execute every single uprising and terror related scheme in Xinjiang (aka East Turkistan and Uyghurstan)’” — Sibel Edmonds, FBI Whistleblower

“And the third reason [the United States is in Afghanistan] is because there are twenty million Uyghurs, and they don’t like Han Chinese in Xinjiang Province in Western China [sic]. And if the CIA has to mount an operation using those Uyghurs as Erdoğan has done in Turkey against Assad—there are 20,000 of them in Syria right now for example, that’s why the Chinese might be deploying military forces to Syria in the very near future [never occurred] to take care of those Uyghurs that Erdoğan invited in—well the CIA would want to destabilize China, and that would be the best way to do it: to foment unrest and to join with those Uyghurs in pushing the Han Chinese and Beijing from internal places rather than external. Not saying it’s going on right now, you didn’t hear that [smiles], but it is a possibility. So that’s why we’re there and I’ll wager there’re not a handful of Americans who realize that we, our military, has decided that for these strategic reasons which are well-thought out, we’re gonna be in Afghanistan for the next half century” — Lawrence Wilkerson, Chief of Staff to former Secretary of State Colin Powell and retired US Army Colonel speaking at the Ron Paul Institute’s Washington conference in 2018
