what would have happened if we never intervened in the german invasion of france and belgium in 1914?

would the russian revolution happen? would germany have sought to conquer it or just to remove it from opposition in the schliefien plan?

would hitler have retired a war hero and never kicked off about the jews? the hyperinflation of the german people (and france when conquered) would never have happened?

wouls britain have been better or worse? better for not having two world wars. or worse for having a massive germany across the border?
