The attack on the Twin Towers was reportedly made because in New York there are multitudes of Jewish people who live and work in New York, and, in fact, there were Israelites who worked in these Towers. The World Trade Center meant International Jewry to the terrorists. The United States is referred by the Islamic terrorist nations as a Zionist Occupied Government--ZOG. Certainly, war and religion are connected!
Look at the Old Testament with all the conflicts and wars, the God of Israel and the idols such as Bahl. The conflict between Palestine and Israel is clearly faith-based. Iran's intense hatred for Israel goes back to the conflicts of Persia with the Israelites. While some wars were under the guise of religion when they were economic, not all wars are economic. Terrorism is modern-day warfare and its purpose is purely religious fanaticism, which has always been dangerous.
