weren’t syria’s kurds also financed by la cia? why would they say that?

Instead of grappling with this dilemma, the Trump administration appears to be making it more acute. As the prospect of near-term regime change fades, both the United States and Israel seem to be flirting with fomenting internal fragmentation as a fallback. Reports indicate that the CIA is arming Iranian Kurdish militia forces in northern Iraq, while Israel bombs frontier posts, police stations, and military positions along the northern Iran-Iraq border to clear a path. In recent days, Trump has suggested he is backing away from this scheme, but Israel has not. Indeed, Israeli leaders seem to view the destabilization of Iran as a preferable backup if regime change proves impossible, potentially pushing Iran into the kind of state fragmentation seen in Libya, Syria, and post-2003 Iraq. In a country of 90 million people at the crossroads of Eurasia, that outcome would be profoundly destabilizing, not just for Iranians but for U.S. interests in the region and beyond.

No one should trust the US at this point, but they can clearly be manipulated for advantage. Never trust an American offering support, but always be willing to use their mistakes to your advantage.
