The centrality of the United States in the world financial system allows it to use that power to cut countries and people off from basic financial services. The United States has long used this power to cut off rogue states, but Trump is abusing this power and the power of the US domestic market, which could lead to a rebellion and weaken America’s power to use these tools when it more needs it.
Trump ran on China being a major threat, but his aggressive actions toward non-China countries, has strengthened China’s relationships with these countries and made China stronger compared to the US.
Trump throws around power to try to get short term gains, not realizing that long term no one trusts him or the US and this ultimately weakens US power.
