The Iron Man book always walked the fence. It was anti-Communist when it first started being published, but quickly switched to Tony questioning building weapons that kill due to the rising anti-war sentiment of the 60's. He's developed weapons for S.H.I.E.L.D. over the years, but I think the character justified that as a way to continue being Iron Man and updating the suit to keep it non-lethal.
