To understand North Korean strategy today, we must first understand the implications of its geography.
Korea is a peninsula jutting southward from Manchuria surrounded by the Yellow and Japan seas. It shares an 880-mile-wide border with China and has a 30-mile frontier with Russia.
Korea’s northeastern border is about 70 miles from Vladivostok, Russia’s major eastern port. The southeast corner juts to within 100 miles of Japan to its south, and the peninsula’s southwest shore angles westward only about 300 miles from Shanghai.
