We should be using this opportunity to determine which must have manufacturing capabilities locally, making that happen, then sticking to it long term for national defense. This doesn't just apply to Japan, or the US, but every country on the globe. Global supply chains are really showing their weaknesses over the last couple months.
Additionally, anything that countries can do to pry away CCP control of global supply chains should be done, with a long term goal of weakening the CCP as they have certainly shown they can't be trusted. They can't be trusted by their people, they can't be trusted by other nations. They've shown now multiple times they will do everything that they can to cover up growing pandemics within their boarders, hide actual infection and death numbers, downplay problems, silence whistleblowers, and lie. Beyond that, they continue to support genocide inside their own boarders, and they continue their aggressive expansion in the South China Sea. They are a bad actor.
