Wars are fought with steel and of words. To fight a thing, we have to understand what we are fighting and why. A blindness in words can kill as effectively as blindness on the battlefield.
Words shape our world. In war, they define the nature of the conflict. That definition can be misleading. Often it's expedient.
The real reasons for the last world war had very little to do with democracy. The current war does involve terrorism, but like fascism, it's incidental to the bigger picture. The United States would not have gone to war to ensure open elections in Germany. It hasn't been dragged into the dysfunctional politics and conflicts of the Muslim world because of terrorism.
Tyranny and terrorism just sum up what we find least appealing about our enemies. But it's not why they are our enemies. They are our enemies because of territorial expansionism. The Ummah, like the Third Reich, is seeking "breathing room" to leave behind its social and economic problems with a program of regional and eventually world conquest.
Islam, like Nazism, makes a lot of utopian promises and pays the check for them through conquest. Like Communism, we're up against a rigid ideology, brainwashed fanatics, utopian fantasies and ruthless tactics. And we can only win by being honest about that.
We are not yet dealing with armies. This is still an ideological conflict. Terrorism is just the tip of a much more dangerous iceberg. It's the explosion of violence by the most impatient and least judicious of our enemies.
