Not shortsighted in the least. The president’s responsibility is to safeguard the country and its citizens. He failed to do so. What if next time it’s a long range bomber from China or Russia? Ignore them as well? And if it was an EMP instead of a trial run? China is not an ally nor a friendly competitor. The US has outsourced most strategic sourcing to China, eg drugs. Stupidity coupled with weakness is dangerous. Pay attention to history. Somewhere Santayana is saying “I told you so”.
