Arguments for cringe: Possibly killed up to 500 Soviet soldiers during The Winter War with the USSR, and is often masturbated to by chuds as a result.
Arguments for based: Him doing this was arguably justified self-defense, as the Soviet Union did initiate the conflict and draw first blood by invading Finland due to them not handing over some land they wanted.
Professionally speaking on the martial side, based. Skilled rifleman who knew how to take into account environmental and terrain factors when faced with an enemy force with greater manpower. A great study on small arms combat in a winter war zone.
Politically speaking, cringe. a propaganda figure created to bolster Finnish nationalism in a period where the reactionary Finnish government was attempting to expand it's territory through annexation of Soviet lands.
Being professionally based and politically cringe makes you cringe.
No amount of aptitude at anything makes up for using that aptitude for evil.
