Fighting war just to get intelligence, without any real threat, is the strategic equivalent of a common tactic being used in Iraq -- reconnaissance by fire. It means shooting at buildings even if there is not target just to see if anyone shoots back. For example, you open fire with 25 mm canon or 50 mm machine gun on an entire Iraqi street. You might kill dozens of civilians huddling in their homes, but perhaps an "insurgent" will fire back, revealing his position. Then you can call in air strikes on the revealed target.
Both are the logical equivalent of 1500s witch trials. You tie someone up and throw them in the river. If they die, they were innocent; but if they float and live, they are witches and burned at stake.
Fighting for intelligence just takes this tactic to the strategic level. Invade, for example, Syria. If there are not terrorists there, you simply blast a path of destruction and murder to Damascus. But maybe somewhere along the way, someone will shoot back and you will have discovered "terrorists".
Here is Ware's description of "reconnaissance by fire":

Journalist Michael Ware is the Baghdad Bureau Chief for Time Magazine. He was embedded in Fallujah during the recent US offensive earlier this month, and has covered the war in Iraq since February 2003. He joins us today with his perspective on the situation in Iraq.

WARE: Oh, absolutely, I mean… For example, the military unit I was with, I mean, the operation in Fallujah involved largely Marines, but also some army elements. I was with one of those elements. The way they proceeded through the city, given that there was booby-traps, improvised explosive devices, riddling the streets everywhere. Entire houses were rigged to blow. The way they proceeded was what they call “Reconnaissance by Fire.” If you’re going to go down a street first you scour it for any potential danger. How do you do that? You do it with a 25mm cannon on an armoured Bradley fighting vehicle. Or you do it with one 20mm tank round. Just blow up everything that looks vaguely suspicious. Then if someone shoots at you from a building, or there’s an explosion near a vehicle, don’t mess with it. Don’t go into the building looking for the guy… just level the building. And then go through the rubble afterwards.
