With Kosovo, they first tried to spin it as a mortal existential threat to the US. When most Americans weren't buying the notion of a tinpot dictator in a country smaller than New York state sending troops in to take Cleveland or St. Louis, they tried a different angle of the Hitler card, i.e. the "genocide" card. They took an ugly civil war with thousands of civilians murdered by both sides, and spun it into a tall tale of unilateral genocide perpetrated by thugs on solely one side against innocent unarmed civilians, solely on the other.
And a hallmark of Neocon wars like Kosovo is that we must care about it more than people who are much more involved. I didn’t see the armies of Europe mobilizing to deal with the existential threat of Kosovo.
Except of course, endless screaming that America should “do something”. And involving a sufficient minimal military commitment to ensure their officers could get joint staff and command duties. That’s very important to Europeans.
