I agree. Plus, as alternate markets are developed, so that leverage drops even more. The US has made friends with a lot of countries based on the goodwill generated by strong trade ties. That goodwill is being eroded in the short term, and will linger as a reputation for "unreliability". 80 years of work is being undone in months. And unfortunately it won't be as simple as "in 4 years we can go back to normal ". It's obvious that congress supports this, and the American people voted for it, so it's not just one man's policy.
