Is it possible to win a war in which the enemy strictly uses guerrilla tactics?

The coalition forces are facing this right now in Afghanistan. The Taliban (and all other Pashtuns that are joining the enemy effort) are using guerrilla tactics. They are not winning any battles but they are gambling that they will win the war by breaking the will of their opponents. Is there any way to defeat an enemy who uses guerrilla tactics and is willing to blow themselves up for their cause?|||You cant win a war against an enemy doesn't fight for a flag. You can kill many of them and you can slow their fight but you wont "win". You wont break the will of someone fighting for a god either. There is no convincing or changing there mind.
