Let's say Truman was able to clinch the Democratic presidential nomination in 1952, while Taft became the Republican nominee instead of Eisenhower. The general consensus here on AH.com seem to believe the race to be a tossup. Who would Taft pick as his running mate? It would definitely not have been Eisenhower given their strained relations at the time. It is also not impossible that Eisenhower would endorse President Truman for re-election.
Alright, let's say Taft somehow wins the election, and becomes President. He would simply be President for a few months before he died, and his stress may even kill him slightly earlier than in OTL.
Okay, my question here is, what would Taft try to do in his rather short presidency? Would he even attempt to withdraw US troops from say Japan and South Korea, and would he manage to get the US out of NATO? While I think both scenarios that I've just mentioned are highly unlikely to happen; would Taft try to improve relations with the Soviet Union, or to push for an earlier detente? What would be his impact on the Cold War? Or alternatively, would Taft have become simply a footnote in US history?
