The administration's tariff experiment has been an unfortunate demonstration that tariffs will not fundamentally change a country's trade balance because they don't change the underlying savings and investment patterns that drive it. Tariffs can cut imports, but they also tend to cut exports (through a stronger dollar, retaliation, and costlier inputs). As long as savings/investments don't change, the trade balance won't either (though certain short-term fluctuations are inevitable).
