The reason for these kind of actions stem from a long time ago, but I think these terrorist acts are very strongly tied to US foreign policy, particularly Reagan and Bush´s (both of them) governments. Therefore Bush´s (actually Perle´s, Wolfowich´s and co´s) doctrines cannot be the cure since to me it´s clear that they´re are the reason. We, europeans should really make EU stronger so we can withstand US pressure whenever the republicans are behind the wheel at the white house and provide guarantees for the ex-east bloc countries so that they don´t get drawn into these "coalition of willings"!
