大将反水？3件事情搞砸了，特朗普无计可施，巴西总统再批特朗普

Group 1 - Trump's dissatisfaction with Federal Reserve Chairman Jerome Powell is evident, as he has repeatedly suggested replacing him, citing issues like the renovation costs of the Fed building as points of criticism [1][3] - The Federal Reserve Act restricts the President's ability to unilaterally dismiss the Fed Chairman during their term, highlighting the institutional independence of the Fed and the checks and balances within the U.S. government [3] - Treasury Secretary Mnuchin warned Trump that firing Powell could lead to severe economic consequences, including a potential 3% drop in the dollar's value and turmoil in the bond market [3] Group 2 - Trump's threats to cancel SpaceX's government contracts were deemed impractical due to SpaceX's critical role in NASA's astronaut transportation and military satellite launches, with a potential breach of contract costing up to $2 billion [4] - The U.S. government concluded that most contracts with SpaceX must be retained, as losing Musk's support would jeopardize key defense and space exploration missions [4] Group 3 - Brazilian President Lula strongly rebuffed Trump's attempt to influence Brazil's internal affairs through tariff threats, emphasizing that no foreign power has the right to interfere in Brazil's domestic matters [6][9] - Lula's government returned Trump's letter, labeling its content as false and offensive, and countered U.S. claims of unfair trade with data [9]
