Land-war proposals here lead back to maritime strategy. French frontier fortifications made a direct attack difficult, while violating Belgium became far more dangerous after Britain ceased to be a friendly or neutral maritime factor. The German risk fleet worsened that problem because its deterrent logic depended on inflicting enough losses to leave the Royal Navy vulnerable to another power. Britain therefore had reason to read German naval construction as a direct challenge to its strategic position. Fortifications, alliance choices, and fleet policy had boxed in German planning before 1914.
