There hasn't been a world war for two thirds of a century now, and US and their trade partners enjoy safe trade routes.
I wouldn't call it "not delivering".
I wouldn't call it "not delivering".
I would call that a total failure by any possible interpretation.
Also, did I understand you correctly: you not only want to cut american military spending, but also keep US morally responsible for situation in Ukraine?... Now, both these viewpoints are to some extent reasonable, if they come from corresponding first principles. But I can't possibly imagine how the same person can hold these two views at the same time: they completely contradict each other. Either US is responsible for events across the globe, OR it shouldn't have a huge military - how on Earth can you believe both?!
And now we have Myanmar muslim situation and Yemen where people are begging for US intervention, but in all probability if we intervened we would be getting criticized for it by the same people asking us to intervene in a few years
We also certainly intervened in Ukraine by fomenting a coup there. Rolling tanks there would probably be WW-3.
None of these interventions has made life better for anyone other than the evil ding dongs at Brookings and in the Pentagon.
African World War (1998-2003). Five million people killed. With nine countries fighting, I think that it qualifies perfectly as a world war.
Bingo, and that's from the Navy and the U.S. Coast Guard actively patrolling GLOBAL waters.
Maritime piracy alone is a considerable economic threat, yes in the 21st century. An estimated 2 BILLION dollars a year is spent on naval operations just off the coast of Somalia (PDF WARNING - PDF WARNING - PDF WARNING http://www.ics-shipping.org/docs/default-source/Piracy-Docs/... )
In this article from 2014 ( https://worldmaritimenews.com/archives/134829/annual-global-... ), again just Somalia, "The OEF estimates the total cost of piracy off the coast of Somalia at US$7–US$12 billion in 2010; US$6.6–US$6.9 billion in 2011 42 and US$5.7–US$6.1 billion in 2012".
Between 2008 and 2012 alone JUST the U.S. Navy responded to 1139 piracy incidents https://www.navy.mil/ah_online/antipiracy/index.html that's an average of 0.78 incidents a day.
It's not just the U.S. patrolling either. China has launched at least 20 anti-piracy floatillas since 2009 http://cimsec.org/chinas-anti-piracy-flotillas-by-the-number...
