Many things will change when Obama is elected. Other things will stay the same. And then there's a third category: things that are profoundly changing, and will continue to change, regardless of who's president. One of these things is anti-terrorist warfare. The war on terror is becoming a war between madmen and machines. A few years ago, jihadis had the upper hand because they didn't mind killing or dying. Now they're being blown away by remote-control pilots who can't be killed. The machines in the sky don't bleed, and they spare us the difficulties of an official troop presence. Pakistan has become the world's first robot proxy war.And so it begins ... Anyway. At least I didn't talk about Obama and McCain to start this week. Just one week to go, my friends. 32. Detroit Lions (0-7). In honor of Jon Kitna's shocking display of humor and self-awareness, a few notes on Halloween. Maybe it's my advanced age or just a lack of social graces, but this is the first time in memory that I haven't been invited to a single Halloween party. (I've even hosted them.) To be honest, this is just fine and dandy with me. It's always too much work to put together a costume, and no matter how far you're willing to go with it — and I'm never willing to go very far — there's someone who trumps you and makes you feel like a dope for even trying. The best Halloween costume I ever saw was four years ago, when a friend went as an Abu Ghraib prisoner. It's difficult to rise above that, or fall beneath it.
