I will always support that any leader that encourage genocide or war should be punished seriously because they are not the once to suffer or die with it gets serious.
Say no to genocide
You say it like it to so so easy forgetting the fact that before such things happen, there is definitely a hidden agenda. The reasons for genocide might not only be for dominance but to control the economy of the weaker state.
Do you think a President of a nation will see an opportunity to lift his nation's economy and not grab it?
So you are supporting that a president or a nation should use because of their own common interest to kill and destroy the lives of people living in another nation, is it only to commit genocide that is a way to lift a nation economy and again I want to ask you another question how does committing genocide to another nation helps that nation grow, you sound like nothing is wrong if a nation is commiting genocide to another nation as long as they are achieving their goal and their country is growing I really don't agree with your ideology because is an evil one.
If you think that punishing the leaders that encourage genocide is not easy then do you wish that they continue committing genocide, killing others and living, you may feel comfortable and free now because it's not happening to your nation or to your family however I want you to remember that if it can happen to others and nothing is done about it, it can also happen to you one day.
