Buddhism and War

A very good link about Buddhist views about war, open here.
Remember, though Buddha preach peace and inspired great leaders like Ashoka, Mahayana Buddhism developed in China and Japan accepts use of violence for protection but always under strict rules and for self protection.
In Sri Lanka where majority of population belongs to the Buddhist branch of Theravada School is under civil war against minority Hindu (Sinhalese).
Very violent attacks happened from both sides, including some terrorist attacks.
