I understand, though there is a marked difference between the couple of dozen European troops deployed in this fashion and the 25,000 US soldiers deployed in Korea.

In any case, the point stands: I would argue that France is willing to put a dozen soldiers in Greenland because it is pretty sure that they won’t be killed by the US, as opposed to sending even a single soldier to Kiev where there is a reasonable chance that they might get killed and we might have to do more than just send money and guns.
