In the context of fighting a war, Kessler Syndrome is a meme. It reduces the expected lifespan of a satellite, but that only becomes strategically relevant if the new lifespan of your satellites is shorter than the war is expected to last and satellites are being destroyed faster than they can be replenished. America is rapidly developing the ability to launch a ton of new satellites very quickly.
Of course the post-war aftermath would be deeply regrettable. But it always is.
