You joke but this was around the time he was coming up with the insanity that was operation unthinkable . So he probably WAS genuinely pissed they were taking away his proposed extra manpower to fight the Soviets.
During World War II, Nazi Germany engaged in a policy of deliberate maltreatment of Soviet prisoners of war (POWs), in contrast to their general treatment of British and American POWs. This policy, which amounted to deliberately starving and working to death Soviet POWs, the bulk of whom were Slavs, was grounded in Nazi racial theory, which depicted Slavs as sub-humans (Untermenschen). The policy resulted in some 3.3 to 3.5 million deaths.
Stalin was joking becuase he wanted to execute 500,000, Roosevelt was joking becuase he only wanted to execute 25,000.
But Churchill was genuinely really pissed they were joking about executing his friends.
his friends and proud patriots
