^short answer, no
long answer & semi-rant
: I believe that war is outdated or more or less "we're tired of this/we've outgrown this" attitude when it comes to the bigger nations, the G8, G20 for the most part. there are always factors leading to war historically. usually it was land, newly discovered or not, religion, and geographical luxuries such as oil or steel. starting as far back as I choose to, religion caused most of the "international" wars in early history. I emphasis 'international" because USA is the first nation/country in the world. of course their have been Kingdoms and empires but never really documented "We declare this piece of land on this paper to be ours and we call ourselves ____" with specific border marked on the land and when they declared this, it was to the known high powering kingdoms and empires like England, France, Spain etc. If england did this decades or centuries earlier no one would give a damn. England is this powerful and holds this amount of militaristic power. Now compare that empire to the Zulu empire, which don't know each other at the time (idk much about the Zulu empire just using it as a frame of reference in this case dont burn me). If they met and Zulu want to fight England back in the middle ages, England would say "you can't take our land look at this document" Zulu would say "well we didn't hear about it" and would kill on. back then they didn't know who was in charge of the world because we didn't discover it all, we do now so nothing is new or surprising
since nations only knew so much about the world and what it offers like steel and coal they can only do one thing which is get more land and they'll fight for it. the new world was discovered, and they all jump ship, Portugal, France, England, Spain etc aka the heavy hitters then and the heavy hitters now, the G8, G20's. but for the first time a certain peoples did something extraordinary. The Dutch didnt want land or deal with fighting away from home and decided to do business. they traded goods and thats amazing. Scholars have traded information about maths and sciences for generations but they never thought of trading mass goods through each other. the savage man in our ancestors would rather kill to get your iron source then trade to get it.
economic systems and ways of life have gotten us into wars before but those were in smaller "not that important" nations. not putting down other countries at all. the world will notice if the USSR and USA go at it. Nipping it in the bud before it spreads was probably the main reason for Nam Korea Cuba etc. both knew that its probably wasn't worth it in the end because of the effects it'll leave for the smaller nations just like mommy and daddy fighting in front of the kids. kids can fight in front of the parents and will be over and forgotten. a divorce has a lasting effect on the family or in this case the world. communication is solving most of the issues the world because people have looked past their background of if their communist and a certain religion. Business is taking place of where religion used to be as in strength in the world. head leaders of a nation are becoming less and less religious because they realized it doesn't change the trading table if you have "catholic" in your profile. money is money and you can't argue that. (plus no country was or has ever been truly communism because Men have greed in them, Kim Jong Ill didn't become the biggest buyer of Hennessy Cognac in '08 or '09 for a reason)
Men are Men so we sin. greed will lead people to go above and beyond to get more. more land, more people, more weapons. there is no more land, borders are established so war can only come from within. we realized that we have more people than the earth can supply. yes I believe its important to have self defense but making more weapons to be put to no use is dumb. weapons are a made by companies and its all a business. Hitler supplied Franco with help for the Spanish civil war to test things and make a profit, Russia is doing the same thing by giving terrorists AK-47's. and they know the US is fighting terrorism but its all business for them. Plus we probably know that Russia is telling the US what they're selling. rather know what they have against us then not knowing anything at all.
Cliffs: No because
-religion isn't as important as it used to be
-we know what the world has to offer, nothings unknown
-we learned to trade everything for once in our sad histories
-Money is the motive now, you don't have to kill to get money
my opinion, I didn't do research, just from memory of what I learned throughout life, correct me on historic facts if you want
