He was ripe for blackmail..
Blackmail did play a part—I think. Why not? This was to neuter Joe and call the shots. See how much China could push him—answer, a whole lot. Now if the Taliban had let the Americans out (as Joe was told) it might have worked. Next, see the Chinese move on Taiwan, North Korea on South, and Iran on Southern Iraq. Russia might move on Ukraine as well. All will use Proxie Terrorist Groups “Isis K Y or Z”, cyber, assassinations, and “Trojan Horse” attacks. Blackmail of Joe, his son, Obama, Democratic Party leaders, and media giants will give them cover to run rampant on the world stage. Looks to me like a run up to WW III.
