I'm not so sure. I don't see a proper hot war happening between the major countries. Three reasons: 1) Everyone is too busy buying Ikea furniture and iPhones. 2) A proper hot war will end in MAD imo 3) The overall mentality has shifted among the 1st world population. Sure everyone is still patriotic but if you tell a German to go kill a Brit/Russian/American they'll think you're mad.
They will don't want to attack other country, sure. But Russian forces are doing just that right now, and you know, under proper propaganda, most Russians support Putin (86% as of the most recent surveys), and think war in Ukraine is organized by Americans.
So regular Russian troops think they're going there to _defend_ Ukrainians from Americans, same as they did in 1968 in Czechoslovakia.
Actually, regular troops appeared there only recently, conflict was started earlier by local pro-Russian people, heavily supported by Russia by means of contract warriors from Chechnya, arms, including heavy: tanks, anti-aircraft systems that brought down MH17, and most importantly -- military instructors (their leader was Russian from KGB/FSB).
So mentality is not a stopping factor there. Before WW2 people mostly thought it's impossible to repeat cruelties of WW1.
I'm Belarussian, so I know Russian mentality. It's not as smart and humane as you're assuming.
I'm from a country with 6x the murder rate as yours (per person) so no my reasoning is not based on assuming people are "humane". Oh and my neighboring country is currently busy with a military coup (Lesotho - check google news - started ~12 hours ago).
My point is bad sht happens. People get shot & die. I can deal with that. A proper hot war is an entirely different beast altogether though & is something I hope to never see.
I can address your specific statements in more detail if you wish but it seems a little superfluous tbh.
Not to this one. Putin's casual delivery of his remarks yesterday about the ongoing potency of Russia's nuclear arsenal was a startling rhetorical escalation, unprecedented in recent decades. I have considered a hot war a strong possibility since the Crimean action in February and think it's a virtual certainty now, and only a question of scale.
I think many readers may find this (non-paywalled) article by Henry Kissinger published yesterday to be worth their while: http://online.wsj.com/articles/henry-kissinger-on-the-assemb...
