Islamic terrorism has roots in Arab nationalism that has risen after collapse of Ottoman Empire. Sure, you can see the fall of Ottoman Empire as a result of Western foreign policy, but even late Ottoman Empire was not such a peaceful place, and committed several well-described genocides.

Since then every country in Middle East existed in one of two modes:

1. Murderous dictatorship (sometimes supporting terrorist groups)

2. Failed state controlled by various terrorist groups.

The only thing the West has arguably been doing in the XX century is moving countries from first category to the second one.

Israel is a happy exception here, although it has many flaws compared to democracies established in more peaceful regions
