Did Germany drive every increase in British battlecruiser size?

Was the rapid growth of British battlecruisers mainly caused by the arms race with Germany?

Global opponents and overseas duties still mattered greatly, although the move from Lion to Tiger is judged more closely related to German construction.

A panel challenge links the growth beyond the first twelve-inch-gun battlecruisers to Germany's building program. The response points to other navies' battlecruisers, possible opponents such as Japan, and the Royal Navy's worldwide commitments. Most German battlecruisers were expected to remain in the North Sea, where the Grand Fleet and its supporting cruisers and destroyers could oppose them. British battlecruisers also made more overseas deployments than the battleships, with older twelve-inch ships sufficient for many of those jobs. The distinction drawn is between the jump to the Lions, attributed more to global requirements, and the move from Lion to Tiger, judged much more responsive to the Germans.
