Unfortunately I don't think they'll ever be a 100% elimination of Terrorism, but I think the best way to fight it is through education.
This next part is just speculation on my part, I have no facts to back them up, but based on where many (not all, just many) of the terrorists backgrounds, it looks like they are from backgrounds where a good education is not easily available (key word good, not just any education), and therefore, it's near impossible for them to get a good job and provide for their family. This leaves many feeling helpless and cheated when they see others living "the good life" so to say. They need someone to blame, whether it be their gov't, the US, the Jews, Christianity, etc. etc. And therefore, many turn towards terrorism as a way to feel like they have control of the situation.
Please understand, I am in no way condoning or justifying terrorism, I'm just stating a reason why some may turn to it. Not saying it's right, though. But, I think if we can do a better job of helping children and adults all over the world become better educated, and therefore, eliminating that feeling of being trapped, or at least minimizing it, I think there will be fewer terrorists out there.
Just my two cents.
