That's what "they" said in 1950.
Then we fought a war in Korea. "They" were wrong".
Then we fought a war in Viet Nam. "They" were wrong.
Now we're fighting a war in Jihadistan. "They" are STILL wrong.
The blood and $#!+ and dirt of war haven't changed since Sargon the Great slogged through mesopotamia ...
Wars are still won by killing people and breaking their things.
The idea that men aren't out there fighting and dying while engaging in the kind of combat he/she thinks no longer exists is both insulting and ignorant.
