Invasion - do we never learn?

Here we go, AGAIN. Nothing every really changes EXCEPT the uniforms.

If only mankind could bloody well grow up and ditch all these acrimonious identity labels.

We only need ONE label, which is called humanity.

All the rest of the divisive political, nationalistic, and religious labels are discordant, need dumping fast and basically divide us all via perpetually fuelling hate.

Do we never learn from the horrific errors of the past?
