Are you kidding? The Sun was more gung ho about the war than just about any other publication on Earth. Seriously, the Sun made most American papers look like war protestors (which they were). LOL! The Sun was practically a combatant. I think it was favorite place to go during the war.
They haven't undermined the war by printing the truth (assuming this is). This Soldier has undermined the military effort through his actions. That's what's happened. Put the blame where it belongs.
