Let this be a lesson to potentially hostile North Korean and Chinese fishermen:

Experts sounded alarm on Feb. 20 over the Japanese military's ability to defend the country after one of its most advanced naval destroyers crashed into a fishing boat, leaving two missing.

The collision on Feb. 19 came as Japan steps up security to ensure safety during July's summit of the Group of Eight major industrial countries, to be held in the northern resort town of Tokyo.

"Japan's security cannot be ensured if an Aegis-equipped destroyer fails to avert a collision with a fishing boat," the top-selling Yomiuri Shimbun newspaper said in an editorial.

Curious how this happened. Being a Navy brat, I've heard my fair share of sea tales. Most USN surface warfare officers will tell you that the "pucker factor" shoots up when you're steering a Navy ship within 5 or 6 miles of another vessel. Granted, we accidentally surfaced a nuclear attack submarine underneath a Japanese fishing boat a few years back, but that was a bit different, what with the whole no "eyes on" element.
