In what ways could have Truman handled Stalin better than IOTL, given the start of the cold war, the lack of initial aggression over the formation of the eastern bloc, the massive Russian spy rings, leading to Soviet nukes, and of course, the Korean War?
Would it have been feasible to immediately start suspecting that there were indeed spy rings all over the intelligence system, and to let Hoover sick the FBI on every last communist or suspected spy in all levels of government?
How far back would you need to go to assure that Stalin would've been unable to make nukes during his time?
If the US had pressured the Soviets for more autonomy over the Eastern states in 1945, would it have produced better results than IOTL?
Could have the US been capable of aiding Chiang's government against Mao's forces, to the point of crushing them, if they wanted to?
And how could've the US avoided the Korean War and force a proper unification of the peninsula?
