However, we cannot blame the tragedies of the past on some leaders and their ideas. It is the nature of huamn who is the main the problem and being responsible for such happenings.
For example, in the 2nd world war, Germany under Hilter started the wars and killed thousand of innocent people. The war machine was not Hilter alone. It was the whole nation supporting the war and most of the Germans were voluntarily joining the war.You can see the smiling faces on the young Germans in the early stage of war when they firstly defeated Russians. The German army was not forced by the secret police to march into Russia.
The mass movement was ignited by the outstanding leaders whom were being trusted by their people.
There are recent example showing that even the educated Americans are also driven by their president to bomb and kill the innocent Iraqis who have not committed any sin at all.
I would like to state that there is nothing can be done to stop such tragedies until the characters of human can be corrected or repaired.
