Well in our Timeline France didn't focus on it's army enough and was trying to be equal to Britain at sea. This stopped them from purchasing new Artillery and made Britain hesitant at landing to help the French when the Germans cut through Belgium.
If the French bought new Artillery and had more men they could have held the line (but might still not win)
This could mean the Russia doesn't get thrown back and smashed so easily and we wouldn't have German troops fighting in the Middle East with the Ottomans to capture Suez.
