How dare countries want pictures of dead Presidents so badly that... they're willing to send real goods to the United States for its consumption, with no expectation of reciprocation.

What's the saying, they've tried nothing and are all out of ideas? Industrial policy is a known and understood thing. The US has this in its defense sector even it doesn't want to admit it, and the CHIPS act was another attempt for the semiconductor industry.
