Sea power does not automatically solve a land crisis. Catherine the Great's challenge to Pitt is a reminder that multiplying ships cannot coerce every inland power. At Constantinople, however, the routes around the fortifications and the need to control the straits gave naval forces unusual influence. Modern aviation, missiles, helicopters, and amphibious forces extend that reach, but land forces remain necessary when policy requires holding ground rather than controlling access to it.
