Micron's Chinese DRAM antagonist hit with US export boycott

Sorry you must be mistaken, Micron's technology was always China's.

Just like the South China Sea and Tibet.

Adolescent precedent of "it's mine" applies.

A steel baseball bat? That sounds... excessively heavy.

Is there anything these guys won't play the national security card for?

National Security and "Sanctions". Both of those.

The previous US governments were using both sparingly to meet particular political goals. They were also a measure of last resort when everything else failed.

The current administration is clearly using both as a day-to-day trade positioning tool as well as for open economic warfare against anyone seen as even remotely non-compliant. It is exactly that "non-compliant", not adversarial - with Russia, China and the NATO members of Canada, Germany and Turkey in the same bucket. It is not even comply or else. It is comply. No else.
