One of his main beliefs was using non-violence as a means of protesting against acts of oppression and using international law to seek justice. This meant he never raised his fists or lowered himself to barbarism however much he was provoked, violated or attacked. In fact this seems to be the opposite attitude demonstrated by all terrorists and most countries (West, Middle East and East) where the belief is that violence and war works. It never has and never will. As Gandhi says "an eye for an eye makes the whole world blind".
As we have now entered the third of the world wars, where the weapons are horrific and the consequences unimaginable, Gandhi's words have never been more important. All politicians and world leaders should read this book. In fact everyone should read this book.
