The consensus I see in most discussions is that Germany may not and Britain shall go to war but France may and Britain will back pedal. I think it is a bit harsh but not unrealistic. The argument is that Britain has grand geo-political reasons to see Germany curbed and Belgium is the casus belli for the masses, cover for the deeper less moral reasons. Frankly, unless the French go full ugly invasion the propaganda likely moderates the look of it, just a corner cut through Belgian Luxembourg, likely much accusations the Germans already crossed the border, the censors suppress any doubts. For me this violation should come sooner once Britain is not sending the BEF, the French 5th needs to get at Luxembourg and cutting the corner through Belgian Luxembourg is the shortest distance. The German Third will moving to flank it as the Fourth meets it. Belgium should attempt to expel both and maybe calls upon Britain. Britain can be in the war for all the right reason, Germany can still play villain, France forgiven for her disastrous faux pas.
