Have you done any research at all? Obviously not. You might start by reading Osama bin Laden's letter to the American people to see what he wants from us. If you read his letter you will note that the first thing he wants from the West is:
"1) The first thing that we are calling you to is Islam. "
As to why the radical muslims hate the West you should read the book, MILESTONES by Sayyid Qutb. He is the root from which grew radical Muslims.
In the Six Days War, Israel crushed a superior force of the Moslem countries. Ayman al-Zawahiri, al Qaeda's number 2 man, worried how that could have happened. The conclusion was that Allah was angry with Muslims and allowed it to happen. They believe they must return to worshipping Allah as Muhammad did about 1400 years ago. They believe Western ways are an anathema and must be destroyed to purify the world.
Therefore, like Hitler, you can't speak to Osama bin Laden in a diplomatic fashion. Lies are part of their repertoire.
