In 2018, there was an incident called the "South Korean Navy Radar Irradiation Issue".(Note: however, that this is the name as seen from the Japanese government's perspective.)

This issue between the Japanese and South Korean governments stemmed from the Japanese government's protest that a South Korean Navy destroyer irradiated a Maritime Self-Defense Force patrol plane with a fire control radar (a radar used in the fire command system).

The term "radar irradiation" is synonymous with "missile lock-on," and is considered a de facto military action.

The governments of the two countries are in direct conflict with each other.

The fact that this issue has not been revisited now suggests that the two governments have either found a suitable "compromise" or have decided to "let it go", or something along those lines.

As a private citizen, I have no way of knowing the facts about this issue.

Well, I also have a lot of new problems that keep coming up, and each time they do, my mind overwrites them and I forget more and more of the old cases.

There are some things in the world that are better left undone -- or rather, you could say that the world is made up of nothing but undone things.

This "radar irradiation" means as same the following

"I see. We must not let this issue go unanswered."

I realized once again the seriousness of this problem.
