Was Britain wrong to enter World War I?

Was Britain's decision to enter World War I a categorical strategic error?

Britain had little room left to remain neutral because France depended on British sea power, and a German victory could have created a much larger combined naval and imperial threat.

Britain had already travelled too far along the path of cooperation with France to withdraw easily. France depended on British naval power, so abandoning it could have allowed Germany to dominate France and gain leverage over the French empire. Britain might then have faced German, French, and Austro-Hungarian resources in a much less favourable balance-of-power setting, with Russia's position also uncertain. The prewar quantitative naval race with Germany may have eased, but a German victory could still have produced a combined fleet threat from French and German shipbuilding. More time for France to build ships, together with changed British-German relations, might have left Britain greater freedom of action at a later date. British signalling is criticised, and the panel treats nationalist Germany as already committed to a course toward war. Entry is therefore judged a constrained strategic choice.
