I was NEVER a fan of Truman, and my aunt was a high fallutin lawyer in Washington DC, who knew Truman personally. I don’t know if she liked him or not, but she did know him. I wasn’t a fan of FDR either. I backed MacArthur.
I didn’t know any of them, and I’m sure MacArthur had his flaws as do we all, but a president openly working with the UN and the opposing side is the very definition of treason.

If it is misunderstood then maybe they should check their
status of command.
