So many problems with the Patton was murdered narrative.
First of all his opinion was not unique in allied ranks, a bunch of generals distrusted the Soviets and did fear that they might try to grab even more terrain than what they did. Some did voice it openly, yet none of them was murdered, nor were they ever banned from writing it in their memoirs etc not in the early period or at any point during the Cold War.
Given that a bunch of people in Washington were already taking a potential conflict (large or small) with the USSR into account and orders came down from HQ to treat the area where they would meet the Soviets as a potentially hostile zone and take appropriate measures. At the same time Soviet movements were being carefully monitored and assessments of Soviet strength was a priority. Of course none of this was made public because they didn't want to antagonize the Soviets any more than the slightly uneasy and tense situation that would develop at the end of the war.
Another main problem is Patton as the mythical invincible general, he was quite competent, but he has been turned into a parody of the actual man and he's variously tagged as the default choice for every top job in the US, including president or Marshall's replacement, while we have very little information about his own post-war plans.
He was apparently so powerful and dangerous that he would be an uncontrollable loose cannon who would orchestrate the full rearmament of the German army and charge headlong at the Soviets right under the nose of everyone else. Something which you can only believe if you ever saw hagiographies of him, which are plentiful enough. Many of his "miracles" turn out to be regular actions, planned in advance. The same applies to his "miraculous" dash to the Rhine, most of the opposition had been mopped up or was busy elsewhere, but people will believe he had to wade through entire divisions of hardened SS elite stormtroopers and somehow used his gumption to find the fuel to move his whole army, whereas he hardly had a few recon elements on hand for a photo op and several units were stuck miles away without any fuel. There is no merit in redistributing your available fuel to a few key units for a photo op and claim you marched your army to the Rhine when in fact you barely tagged it with a ten foot pole.
And nobody found his death was in any way weird, until somebody writes a fiction in the 1970's and when the conspiracy finally gets traction we get stories about crazily complex plans to disguise his death as an accident but doing it in such a way it could have gone wrong a million times over
And suddenly we hear that everyone whose name is recognized by more than five people is apparently implicated. Stalin because he feared that Patton would drive all the way to Moscow to personally lynch him, Eisenhower and Truman and even Churchill who apparently had so much power that every enemy commander was his own personal hand puppet and orchestrated the entire war for his personal glory …
It's the perfect conspiracy for the true believers of the Patton Myth, who don't want to see him die ironically and then imagine a future so bright and controversial he could only have been murdered by lesser men who despised him …
Patton never really made his post-war plans public to a great degree. He didn't wish to remain in Europe and expected to get a last job in Washington or if nothing was forthcoming to retire. He never expressed much enthusiasm for politics and probably would need some prodding to get him to run for any position.
He might have gotten the job of Superintendent at West Point, though he devoured military history he was never an academic at heart, so it all depends on his own whims.
It seems to me that Patton fully understood he had a pretty full legacy and he while he was a larger than life figure in what he did, he was wise enough not to want the whole world, unlike say MacArthur …
