Terrorism
If the word "terrorism" means "the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political aims", I wonder what the political aims of the "terrorists" are. Are their aims being realized, or not? Terrorists do not employ weapons of mass destruction, and their tactics are intended to arouse "terror" among you. You should not fall prey to terrorism. You can kill terrorists, but you cannot eradicate their ideas by killing them.
You tend to classify people into "we" and "they" without justifiable criteria. The point is that "we" tend to fall prey to "our" ethnocentrism as well as "their" ethnocentrism. I think that the purpose of terrorists is not killing as many people as possible, but arousing "terror" among you to accomplish their goals. What are their goals? You should not fall prey to terrorism. Indiscriminate bombing, for example, kills not only "terrorists" but also local people and "prisoners of war."
