I don't know. I am confident that money will find a way. Look at the cost of the Ukraine war on China as well as Russia. It is in no one's financial interests to commit to a war these days. Putin is indicative of the world's weak spot. When individuals use their state for personal gain, everyone looses. If the world used a combined effort to prevent invasions by forcefully pushing invaders back into their countries, then even these types of actors can be neutered.
