Calling soccer "The Beautiful Game" is nothing but pure unadulterated marketing at its best.
I don't like the term "War Room" either. I'm not a war vet just a regular old peace time vet. But words have meaning. In the "War Room" if you have a bad day, you get fired with the rest of your contract paid and get a job with another team. In a real war, if you have a bad day, you get killed or your legs blown off. Your kid grows up a drug addict because he had no father.
It also cheapens the word "war" which is probably why Amercians are always ready to send someone's else's kids off to war
