I am suspect of retired high-level military support.
One thing I got out of 'The Patton Papers 1940-1945' by Blumenson was that Patton said he would have to resign, not retire from the US Army or he would be muzzled by the government; he was planning to run for President on an America First ticket when he died. A man of such driven caliber, little short of death would of stopped him from succeeding in this objective.
He was quite a 'conspiracy theorist' in the end; he was convinced that the US Army was “killing the wrong sons of bitches [Germans]…the result of a conspiracy of international bankers and labor leaders and Jews and Communists, all whom were working for the downfall of the United States.” (The Patton Papers 1940-1945, p. 735).
General Patton knew most of the players personally, Bernard Baruch, Harry Hopkins, FDR, Winston Churchill, Samuel Untermyer, Joseph Stalin; he help facilitate the Casablanca Conference (SYMBOL) although Stalin was not in attendance.
Patton shared that folly of many, he could not separate high level Zionists from world Jewry, take that into consideration when you read his memoirs.
