Against France.
We went to war because of our treaty obligations to protect Belgium neutrality, the other parties went to war due to their own treaty obligations.
You wanna try unpicking the riddles on R & S, like nailing jelly to a wall!
If we had sided with Germany, the exchequer would not have been indebted to America, America would have continued with it's policy of isolationism, the empire would have remained intact but political, social and economic reform would have slowed.
I went to the Imperial War Museum in London today.
One thing I found out about the first world war was that Germany supported the Boars in the Boar War, and this drove us to dislike Germany even more, and that led us more into the arms of France/Russia, who had a pact against Germany.
I never knew the Boar war had an impact on the first world war.
That's true VHG, but America was also very sympathetic to the Boer cause and it was only the Spanish American war of 1899 that their and subsequently German and probably French intervention.
Also Portugal allowed Boer munitions to pass through their African possessions and Portugal was an Aliied not a Central Power in the first Great War, our historical allegiances with Germany far outnumber our battles.
