Tancredo had it correct when he stated that the real issue was Islamic hatred for everything non-Islamic. No, he only stated one common part of a much larger issue. for attacking the other nations in the world, Spain, Germany, France, India, etc. Do you know the history of these countries? And their history justified the attacks on them?
Tancredo stated the essential part, which is hatred for anything Western.
The radical Muslims attack because they can, just like the Communists and Nazi's.
The only thing they understand and respect is force.
