Missiles first, talk afterwards

As we teeter on the brink of yet another war one is faced with the unpredictability of how democracy throws up its leaders and how close we become to placing people in power who should be unacceptable. John McCain has been extremely bellicose in his challenge to President Obama's softly softly approach to the trouble spots in the world.
If words were put into action we would be scrapping all over the place, his mindset seems predicated on teaching anyone not gifted with  an American passport, a lesson in American supremacy. Missile first, talk afterwards. He came very close to having his finger on the button and there seems no way of screening out this propensity for action in the system of democracy we currently have. 
Its no use saying we can vote him out after he has annihilated the world !!
