The choice is not between intensive bombing and doing nothing. Nonviolence seeks a creative third way . Nonviolence avoids the use of violence. Using more violence can only intensify the conflict and make a negotiated solution even harder to find. An intractable conflict with centuries of bitterness behind it is not going to be solved by yet more violence which can only add yet another level of hatred.
Nonviolence always respects the other.
Demonising the Serb people is only making the end solution even harder to find. In order to end a conflict it is essential to seek to understand the belligerents, and every misrepresentation erodes understanding. Most conflicts arise out of fear rather than inherent wickedness, and we must seek to remove this fear not intensify it. Finding understanding will involve listening to the reasons why people are behaving as they do, and helping those organisations who are working to allow such listening to take place. Nonviolence never humiliates.
