AHC: US president who is okay with full escalation of Korean War into WWIII

I need a POTUS that is both capable and willing to ramp up the US military-industrial complex and anti-Communist aggression, leading to full escalation of an early proxy war such as the Chinese Civil War, Greek Civil War or Korean War into WWIII.
POD starts in 1941 but must be strictly limited to US domestic politics. Ideally becomes POTUS through peaceful elections in '48. Could be either Truman/Dewey/Thurmond becoming radicalized or another candidate running.
