That was probably what finally propelled Eisenhower to the Republicans. Or maybe people didn't know that

I guess you didn't know that Eisenhower hated MacArthur since his service under him in the Philippines in the 1930s.

Ike was a witness to every bad thing ever said about MacArthur, and if Ike had been President instead of Truman (which, if he had run in 1948, he would have been), he would have relieved MacArthur much sooner.

I was well aware of the animosity between Eisenhower and MacArthur, that was why Roosevelt kept them half a world apart in the Second World War.

Eisenhower was repelled not so much by the injustice done to MacArthur (probably thinking it was only fair comeuppance), as by the callous disregard Truman (and the Democrats as a whole) had for the collective wisdom of the military in the art of warfare.
