That's putting it mildly. Threatening to invade allies justifies stronger words.
And yes, most consumer goods from everywhere come from a Chinese supply chain ... but we're not talking about consumer goods here. We're talking in this case about military purchases. There aren't many western countries buying military hardware from China.
Saying that products with US based supply chains are rare does not somehow detract from the point of moving away from the ones that still exist.
And they do exist, just not for consumers, or at least not at a price most people are willing to pay.
Nobody cares if their dollar store trinket was made overseas. And nobody would buy it if it was made in America because that same trinket would cost 5x.
People barely even care about their privacy these days, it seems.
But governments still seem to care about their military independence in the rare event they are at odds with an ally.
