Actually bought this book but not read it as it's packed with a ton of other stuff since I was moving and.. Anyways, this has a good synopsis:
"'A Mosque in Munich': Agents of influence turn a German mosque into ...

Jun 5, 2010 - Bruce Ramsey. Special to the Times. 'A Mosque in Munich: Nazis, the CIA and the Rise of the Muslim Brotherhood in the West'. by Ian Johnson .."
Basically, the Nazis attempted to utilize Moslems in Germany from Central Asia to foment trouble back home as proxies against the Soviets.
During the Cold War, the CIA & West continued to use what started there to spur nationalism and religious fervor amongst them as a means to also halt the spread of Communism in the Middle East and against Nasserism and its dream of a pan-Arabic state. Last thing our oil companies wanted was a unified Islamic bloc in the region.
We utilized Wahhabism - radical Islam - for this, encouraging its growth and spread.
Reagan funded Bin Laden $1.5 billion to create what became Al Queda to fight against the Soviets in Afganistan, giving them CIA training which they ultimately used against us.
From Britain and Russia using divide and conquer tactics to split apart Persia during the Great Game to the CIA's coup to arrest Mossadegh and end Iran's democracy in 1954 for the sake of British Petroleum Oil, you can understand why that country is a tad miffed at us.
Ditto for splitting Turkish territory into artificial countries in which we have continued to instigate anatagonism between various religions and ethnicities to keep them verging on unstable, propping up brutal dictator/puppets, to Israel, to our invasion of Iraq for a lie... we've gladly helped to start factions fracturing all the while thinking tweeking trouble just a wee bit more is all it'll take to sew the whole mess up,,,
Not saying that justifies terrorism, but there's a reason this stuff wasn't happening prior to WWI, and that reason is us.
You said something below about one on one them saying... Sadly, much of that is telling you what you want to hear. Yes, parts of the koran advocates hatred, and there are cultural aspects that cause them to have a certain disdain towards the West. Integration is superficial, as they have literall walls to keep them apart from their own next door neighbors, thus the notion of community is centered around what can be gotten from it. Most don't like us.
