So how can the lunar surface, that's been hit so many times, that it looks like a major nuclear war occurred there, yet we never see any major impact events, or evidence of a recent impact events?

Keeping watching. Maybe you'll be the one who sees the next lunar asteroid impact and be famous. Activity has slowed considerably in the past few [couple billion] years, but there are still asteroids and there have been some near misses lately. Tiny ones hit all the time, especially during meteor showers. Next major shower is due to start in a couple of weeks. Mostly comet dust, but there might be a larger chunk in with them.
