Ah yes, the "globalization ensures peace" theory. I suggest that as globalization peaks, as it did just before 1914 and 1929, that the subsequent breakdown in globalization leads to war.
US companies made a boatload of money from selling to the Nazis before WWII.
As complex systems breakdown, sovereign interests take over. Decisions are made incrementally that lead to war. World wars are not planned, rather, they materialize from a series of bad decisions and unanticipated events that eventually make policymakers lose total control.
And then, when the population of any given country gets pissed off because its living standards have plummeted to third world status, you think the next guy they elect President will care about IBM's India market, or GM's market share in China?
They won't, and the system will continue to breakdown... Smoot-Hawley - that kind of stuff. A reversal of globalization - currency wars, etc...
And then, to maintain some sort of economy, resource wars, fought by proxies develop... until someone begins to lose, and the proxy wars give in to actual wars, fought between major powers, in unconventional manners.
