Why would the sky be falling? Getting the world's largest economy to prop up your own economy is kind of the point to being an ally of the biggest economy in the world; the Japanese and American governments being in bed together and planning the Japanese economy is not just normal, but is one of the bigger conspiracy theories persisting from the 1980s when US intervention is blamed as the reason Japan's economy stagnated in the 90s. So I don't understand why this would be a sky is falling moment.
