As much as one wants to believe our government would not have one of its greatest warriors iced, both his popularity and outspoken anti-communist views certainly would have been a huge impediment to the post-war agreements hammered out a Yalta. We're only now coming to grips with (and paying for) the level of communist infiltration into western diplomatic and intelligence circles. I can't say definitively that the OSS killed Patton, but I think it would be safe to assert that there's more to the circumstances surrounding his death than has been publicly aired.
There are Soviet figures in the picture, as well as the vast pink underbelly of the Washington Administration which gave Eastern Europe to Uncle Joe with a bow.
OSS was duped by the NKVD in the rush to be allies against the Axis.
Gehlen was penetrated, and his bunch absorbed under Operation Paperclip enjoyed a special relationship with OSS and CIA for fifty years--such is the Agency's own admission.
Patton was loud about it. He was removed.
China fell; Korea presented as low-hanging fruit.
They could have waited until today when they have one of their own in the White House.
That premise is easy to accept if you also accept, which I do, that our government we see or are allowed to see is like the 10% of an iceberg above the water.
The part we see gives us just enough not to create waves and make us feel good about our "way of life" while the ruling, not governing, and self enrichment is done out of sight and hearing from all except the select members of the inner circle.
Anyone threatening the inner circle becomes a member of the expendable list.
