Q4) To finance current budget deficit, US government relies on T bond sales. The significant portion(over 30%) of T bonds are purchased by foreign governments or capitalists(lately China). What is your opinion about relying on foreign debt to finance US budget deficit? If some foreign countries became unhappy about trade or political matter with US government ( of the new president, Biden) or due to lack of confidence over US T Bond and decided to cash out (sell) US T bonds they are holding, what economic consequence do you expect to be occurred?

Q5) US national debt to its GDP is a little over 100%. Japanese national debt to its GDP is getting close to 250%. Could this be a potential disaster for the global economy ,since Japanese economy is 3rd largest one in the world? or do you think US does not need to worry about its own debt, considering its own size of economy(GDP)?
