If you've never seen one of his temper tantrums nor heard his bizarre theories about war, you won't know what we're in for, if he ever get's in the white house. He is just as dangerous to world peace as any neo-con.
McCains superficial personable quality and the hail fellow well met affability of a lifetime naval aviator sells well. He is also intelligent and articulate.
People make the wrong assumptions about McCain. Because he was a war hero, exposed to the dangers and tribulations of a combat pilot during Vietnam and tortured as a POW, doesn't make him competent to be commander in chief. In fact it is just the opposite. He is very disturbed by his negative experiences.
His entire mission will be to to prove that we could have "won the war in Vietnam" by trying out his theory on some other poor nation. In this way, he is the essence of what is wrong with the neo-con clique. Hitler's disciples believe that Socialists sold Germany out during WWI. The humiliation of WWI was instrumental in causing WWII. PNACers and McCain are similarly motivated by an equally bizarre and incorrect analysis of what was wrong during the Vietnam conflict, leftists at home sold us out. If we had only "taken the gloves off" and "flattened Hanoi" and "bombed Vietnam back to the stone age" we would have won. Several hundreds of thousands of tons of more bombs dropped on people and several hundred thousands more troops would have assured victory. These are the innermost beliefs of John McCain. The war hero couldn't possibly have less insight into the nature of that war or the war in Iraq.
McCain is a time bomb waiting to go off, in more than one material sense.
