It won't get to that point as both France and Britain will be militarily exhausted. However I expect a definate chill in post-WWI diplomatic relations between those nations.

France and Russia promised to do the bulk of the fighting on land. France held up her end of the bargain until after Russia died, allowing the French army to be overwhelmed.

Britain promised to do most of the fighting at sea. And failed miserably from 1915 onward as Baron Letters continually kicked their butt. That's not exactly true, but it is the way the French people will view events.
