Does Islam promote violence and terrorism?

No. Islam is religion of peace and submission and stresses on the sanctity of human life. A verse in the Quran says, [Chapter 5, verse 32], that "anyone who saves one life, it is as if he has saved the whole of mankind and anyone who has killed another person (except in lieu of murder or mischief on earth) it is as if he has killed the whole of mankind." Islam condemns all the violence which happened in the Crusades, in Spain, in WW II, or by acts of people like the Rev. Jim Jones, David Koresh, Dr. Baruch Goldstein, or the atrocities committed in Bosniaby the Christian Serbs. Anyone who is doing violence is not practicing his religion at that time.
However, sometimes violence is a human response of oppressed people as it happens in Palestine. Although this is wrong, they think of this as a way to get attention. There is a lot of terrorism and violence in areas where there is no Muslim presence. For example, in Ireland, South Africa, Latin America, and Sri Lanka. Sometimes the violence is due to a struggle between those who have with those who do not have, or between those who are oppressed with those who are oppressors. We need to find out why people become terrorists. Unfortunately, the Palestinians who are doing violence are called terrorists, but not the armed Israeli settlers when they do the same sometimes even against their own people. As it turned out to be in the Oklahoma City bombing, sometime Muslims are prematurely blamed even if the terrorism is committed by non-Muslims. Sometimes those who want Peace and those who oppose Peace can be of the same religion.
