I find it hard to believe that as militaristic Germany would have been much different in victory than a militaristic and rapacious capitalist Britain. moreover it might have averted a murderous Nazi state and similar Stalinist state. it would have dethroned the british empire but few outside of Britain would have suffered.
what I lament is Canada didn't have the independence of mind to stay out. there was no benefit to anyone in Canada to anyone winning, and the French Canadian opposition to imperialist military service created national divides that still exist.
in addition several Canadian regiments were wiped out as expendable cannon foder for a cause they could not benefit from.
of course a german victory might have stunted the French cultural leadership of Europe. as the arguably most culturally advanced nation that might have been a disaster.
then there was the destruction of the liberal class in north America which has never recovered. read "the death of the liberal class" by chris hedges.
