McCain's instinct is to always go to war. Is that what America wants, more wars?

While a tough guy can be reassuring, he's less reassuring when it's your child he's sending to die because "we're all Georgians."

At rare moments in history, a military response is essential and required, as it was in World War II, and as it was in Afghanistan in the wake of Sept. 11.

But more often, the choices offered by history are more complex, requiring judgment and wisdom. Choosing confrontation and war too quickly when other options are available can prove disastrous, as the example of Iraq should have taught us.

McCain’s instinct, demonstrated time and again and most recently now in Georgia, is to cast America as a global policeman. In the next few months, American voters have to ask themselves whether they share that vision and instinct.
