Take care of the Wave problem

They say that when all you have is a hammer, all problems look like a nail. Wait, the proverb seems wrong. Maybe the correct one is the nail that sticks out, gets hammered down? But you digress.

When you have kage bunshin, everything you do can be delegated to kage bunshin as well. You mastery over the jutsu has allowed you to create clones that last for a long time. As a result of that, you have a lot of information that helps you to take action, or in the shinobi parlance, intelligence.

So, the easiest way to treat the problem is to treat the symptoms, not the source. While that sounds blase, Wave's economic problems didn't have a single solution that would take care of everything just like that.

Treating the symptoms is easy. All three conglomerates are fighting among each other? You sent your clones to take care of each group's top three leaders simultaneously. Taking then out served two purposes, which was to sabotage the groups' operations, as well as serving as a warning to them to tone down with their power rivalry lest foreign forces such as Konoha takes notice.

Less than thirty minutes after you send your clones, their memories began coming back. The leaders were taken care of.
