TR: How prepared are we to deal with chemical and biological agents compared to ten years ago?

Cote: The means of dealing with chemical and biological weapons really hasn't changed. People forget that chemical and biological weapons are really old technology. The military has been developing ways to protect soldiers from these agents for a very long time. From the military's point of view, dealing with chemical and biological attacks isn't rocket science. But that doesn't mean it's not extremely inconvenient to wear those suits. Supposedly we have better and lighter suits, but still, the bottom line is that it's inconvenient and to be avoided if possible.

The issue of chemical and biological weapons really has more to do with terrorism against civilian populations. In that sense, it's possible we may see that in this war. There's still speculation about what Iraq has, but it clearly has less than in the first Gulf War, especially in terms of delivery capabilities. On the other hand, Hussein has more incentive to use them.

TR: What about communications? To what extent are soldiers, ground vehicles, and aircraft better networked?

Cote: We're still a long way away from exploiting it, but we're a lot further on than we were in the Gulf War. There are now data links between tanks where they share images and locations and things like that. For the individual soldier on the battlefield or in urban combat, that's still far off.

The whole issue of advanced networking and communications really becomes essential when you start talking about mobile targets. It's possible that this war will demonstrate the first really big major successes against mobile targets. What we may see here is that networks of persistent sensors and precision weapons will give us capabilities against mobile targets that resemble the capabilities we now have against fixed targets-which is, basically, if we find you and decide we want to attack you, we're going to. We can't do that yet with mobile targets, but we'll be demonstrating in this war some nascent capabilities in that area.

An example of that will be the persistent surveillance by unmanned aerial vehicles, or UAVs, over battlefields pumping info back in real time to a headquarters. We've already seen that in Afghanistan, and we'll see a much bigger payoff here. The big payoff will be our ability to go after these mobile targets, and our ability to stare at one thing for a long time if there's an item of interest there.

TR: Could there be negative consequences if the war goes too well?

Cote: The main negative consequence might be an over confidence in our abilities. If the war goes really well, it will be because large sections of the Iraq military decide not to fight. Then you draw the lesson that this is likely to occur in the future if we go after someone else. Here you set yourself up for a real disaster.

For countries like North Korea and Iran, that scenario is less likely. In Iran, the regime is legitimate. There's intense nationalism. North Korea is more complicated. The government isn't legitimate, but the regime is not losing its grip. If you're in the North Korean military, you are insulated from the worst aspects of what it's like to be in that country, at least in terms of material want. So you get loyalty from that alone.

So the big danger with success is hubris.
