Ah, my apologies. I jumped to the conclusion that you were echoing Trumpian bombast about unprecedented peace and prosperity. Bad zftcg!
Anyway, if we're talking long-term, I'm mostly with you on peace.
The historical trend has been that the scale of conflict has gradually declined over time. I think there will always be some level of conflict, and what I mostly want is leadership that will help us successfully navigate us through them without making them worse, and also who will have the long-term foresight to address issues that could cause us big headaches down the road. (To cite one example, think of how much the Syrian refugee crisis has done to destabilize governments around the world in ways both big and small; one could even argue that it contributed indirectly to Trump's election. According to some estimates, climate change could end up producing refugee crises that are orders of magnitude larger than what we've seen over the past few years. That's going to lead to lots of lots of wars and other problems.)
As for prosperity, I'm much less bullish. Globalization is doing a real number on our economy, and I don't think either party has done a good job of being forward-looking and adapting us to the new reality.
