Britain was not about to do that because Belgium was trying to remain neutral, but Germany invaded it anyway, violating the Treaty of London. Britain wasn't about to allow Germany to take control of the coast and waterways leading into Europe. Germany began bombing London on May 31, 1915, and continued until the summer before the war ended.
If it wasn’t for France’s stupid alliance with Russia, the Germans wouldn’t have had to invade Belgium.
Why did the French care about who won between Germany and Russia?
Nicky deserves a lot of the blame for starting the war, too.
