As I recall, the Brits joined the frogs on the continent to repel the Huns

The Brit mainland was never threatened.

On the Western front, France was the objective. Belgium was just in the way of the German attack

Germans put a naval blockade around England shoothin anything that moved. Being an island, that would destroy England if successful.

WW I

Correct

WWI is a mix of issues, none of which was "destroy perfidious Albion"

• The dissolution of the Polish-lithuanian commonwealth in 1791 put the Germanic world bordering the Russian one and set the pace for competition. This was kept under control by Bismarck, but the struck-by-inferiority-complex Kaiser Willie II broke that pact and created the Franco-Russian alliance
• Under Bismarck, the French were isolated (he remembered the napoleonic wars when France devastated the German lands)
• The British were closer to the Germans - heck their royal house had been german for 2 centuries
• Willie unnecessarily went into a naval race and a colonies race that Germany did not want or need
• The Russians were also eager for WWI to conquer constantinople and the Balkans and they had the mission of "reuniting Slavdom and all the Orthodox under the 'benevolent' rule of the Tsar" - so a three-way mission (unite the Rus, unite the Slavs, unite the Orthodox)
• the UK was playing its old game of "keep them divided - ally with one against the other"

The German plan was to knock out France, push Russia back to the Brest line and prop up Austro-Hungary
