If Patton had green light things could have been different:
In early May 1945, as the Allies shut down the Nazi war machine, Patton stood with his massive 3rd Army on the outskirts of Prague in a potential face off with the Red Army. He pleaded for General Eisenhower’s green light to advance and capture the city for the Allies, which also would have meant containment of the Russians. British Prime Minister Churchill also thought the move a crucial and beneficial one for post-war Europe and insisted upon it, but to no avail. Eisenhower denied Patton’s request, and the Russians took the region, which would pay dearly for years to come. Earlier that year, at the February conference in Yalta, President Roosevelt, with Churchill at his side, extended the hand of friendship to “Uncle Joe” Stalin and signed his Faustian pact. In so doing, the destiny of millions was reduced to mass starvation, blood revenge, and distant gulags. At the time, Patton understood the tragedy of this event and wrote, “We promised the Europeans freedom. It would be worse than dishonorable not to see that they have it. This might mean war with the Russians, but what of it?”

A large reason I believe Patton was murdered.
