There have been such reports. However, their very nature makes them subject to the expectation and risk of a self serving bias. They all must be second and third hand at the least.. Inasmuch as they fail to impact our own reality at all, the war simply fails to exist.
Certainly we have evidence that our own near earth space fleet actually exists. Again it is kept secret and we know nothing we can verify. Are we actually part of any such conflict?
What bothers me is that humanity threatened is soon humanity united. This is an asset. Why are we not exploiting it.
Is there a Space War?
