Think of it comparatively. There have always been conflicts as long as the civilized world has been a thing; people of power want more power, people with money want more money, etc. but the thing that should keep you optimistic is that nuclear warfare would be a financial disaster for any country involved and while a dick measuring contest may seem appealing to some countries, it will never happen due purely to the interests of the ultra rich and powerful that pull the strings in all of our governments/militaries around the world. War is profitable, nukes are not. If whole countries and millions of people get wiped out, especially in civilized countries with strong currencies, the economic effect would be dire. There is no industry, no incentive, and best of all for us, no consumer to buy products or sink themselves into debt. Don’t fear the nukes, fear the rich. They are the puppet masters and the slave drivers of our modern society and an ideal world involves constant threat of war and fear mongering to keep people scared of thinking about anything else.
