Maybe we don't need rough men, but men who won't let themselves be sold as fools for yet another geopolitical proxy war. A war with questionable (and arguably even negative!) results for our all safety. Because if we look at the last 3 decades of war, I am not too sure if the net result made the world a safer place. Yeah some geoplitical or monetary interests got defended, a lot of people made money, a lot of people lost their lives, many war crimes fuled a entirely new generation of terrorists, but if this would have been about saving lifes the money would have been better invested in healthcare or the prevention of future pandemics.

If some level of violence is necessary to ensure peace, the people entrusted with the power to inflict said violence should be compassionate and wise humans not, "rough men".

And at the same time we should be putting our resources to work at lowering that necessary level of violence.
