The United States among many other countries offered their immediate help concerning all three entities. Earthquake, Tsunami & Nuclear Power Plant. Especially the latter. Japan’s response was they didn’t need any help. In my view that was pompous egos. Accepting help wouldn’t have meant that Japan was completely unknowledgeable of what they were doing. On the contrary Japan has had the most intelligence in this area, but have definitely made some mistakes of how they built these reactors so close together. But considering the country just got hit with the fourth biggest quake in history and a disastrous tsunami on top of that, protecting their countries citizens not their egos should have been their first priority.
