How about getting real with the understanding of human nature? The world you wish for does not exist. Go tell your idea to Putin, Xi. Kim, Hamas, Hezbollah, or the other instigators of violence. Either you defend yourself and resist or you become a subject of an antichrist dictatorship. There is no other choice. There never has been. There is always some antichrist dictator ready to attack at any sign of weakness. Before there were guns or swords, they used sharpened rocks.
Would you put on a uniform if the alternative was death or enslavement? Turning the other cheek does not mean that we have no right to defend ourselves against agression. After all, Americans arm themselves to the teeth in the vain hope that they will have an excuse to declare war on the government of the day.
Your day may well come. Modern youth are so pathetically weak, mentally unstable, drug addicted or physically incapable that few would be able to fight anyway. Xi will send in his troops and that will be the end of it. There will be no more war, but is that the kind of peace you want?
