NO. Deterrant works when everyone accepts. if only one side accepts, the other side must adopt the same principle or else risk extinction.
even though we all know non violence is paramount, if one side gives up weapons and the other side doesnt - the certificate of honor is not going to save the former side when the latter attacks. what might save the former side is not giving up weapons.
so such things are never done as a gesture. it should be done as a treaty where both sides agree to it , together on a common platform.
proactive gestures are done by the weak or the stupid.
i think we should give up the charade of upholding democracy. both sides want democracy only when they are not in power and fascism when they ARE in power. One should just accept and normalize this thought. There is no need to expect democracy at all when it is just an excuse. one should accept and understand that fascism is how it is and always will be.
