Roosevelt kept American naval growth from becoming a British rivalry

The United States had greater latent industrial power than Germany, a long land border with British Canada, and a much larger population and army than Canada. Those conditions could have made American naval expansion deeply alarming in London. Roosevelt framed the fleet around the Monroe Doctrine, American world standing, and professional courtesy. That approach contrasts with Tirpitz's personalisation of Germany's naval challenge. The later Empire Cruise returned the courtesy through public calls at Honolulu and San Francisco while pointedly avoiding Japan, showing that friendly and omitted visits both carried strategic meaning.
