"Who considered their enemy"? What are you talking about?
I knew these people for years and lived among them. They most certainly did not consider me or any other American as their enemy.
Achenese are very open and accepting people. They are not Arabs.
I am considering the Asian Pacific Rim countries, all of them that were effected. Many are dominated by Muslims. I understand (correct me if wrong) that OBL was considering ACEH for relocation plans. That AQ has established a foot hold there and in other rim countries.
