The scientific concept, dictatorship, means neither more or less than unlimited power resting directly on force, not limited by anything, not restrained by any laws or any absolute rules. Nothing else but that.
-- Vladimir Ilyich Lenin
Without the restraints of real legislation or of the natural and permanent moral laws we are left with one thing--the law of the jungle--to kill or to be killed.
It is impossible to reason with, negotiate with, or otherwise peacefully coexist with any person, any group, or any nation, that believes that it has the right to control you or to take things from you by force. Such persons or entities can only be physically isolated from you or ultimately destroyed.
Peace is the absence of enemies but it is not, as some wish to believe, priceless.
As long as there is one Communist who lives there will be no peace. This also applies to Islam.
