Alan Moore's Watchmen series used the same trope, and indeed, the idea of a (fake) alien invasion uniting the planet has been used in science-fiction for decades. In some cases, the plot fails: in the Outer Limits episode, it fails because Culp's spaceship goes off course and is discovered by three hunters, whom no one believes. In Moore's Watchmen comic, the plot succeeds until another character's journal detailing the whole ruse is discovered at the end of the story, with the implication that this will reveal the deception and thus end its usefulness.
The idea seems to be that while unity and an end to tribal conflict is a good thing, it can't be accomplished by trickery. If we want to end our petty squabbles between nations and between ourselves, we're going to have to decide to do it on its own merits. Any attempt to foist a false external threat onto humanity and thus make us unified will eventually fail because the ruse will be discovered.
But, as they say, the truth is stranger than fiction.
I won't say the Coronavirus is a species-ending threat to the human race. It is serious, and we need to take relatively drastic steps to contain the threat, but no one is predicting that the virus threatens the survival of humanity itself. Still, it does represent an external threat, one which in no way respects borders nor ideology. And it is a serious threat.
I would have hoped that in light of this threat, we would have found a way as Americans to stop the tribalism. I would have hoped that there'd be an end to partisan sniping from members of government. I would have hoped that there weren't accusations from the leader of the free world that the news media is hyping the pandemic to hurt him personally. I would have hoped that, finally, with this external threat, we would have put away the childish words and deeds of the past and focused on the threat itself.
That, I now see, was too much to ask.
If I were coaching against some opponent--let's say one that for some reason my school had a rivalry with--and a fire broke out on the field, I wouldn't be looking to see how I could turn the situation into my advantage. The two teams, who had been opponents when the game started, would turn into allies as we fought the fire with our water buckets and squeeze bottles. We'd recognize that the fire is much more serious than the game we had been playing.
What if tomorrow, we detect a fleet of interstellar spacecraft approaching the planet, sending an alien but unmistakable message of warning to us? The Day the Earth Stood Still played on this idea, too. Would our president claim that the aliens were sent by the fake news media to tear him down? Would he tweet in all capital letters, "SAD!"?
What if Jesus Christ came back--or came for the first time, depending on your beliefs-- tomorrow? Or Mohammed? Or any of the many messiahs claimed by the world's religions? What if they ALL appeared? Would some people criticize the Lamb because he wasn't wearing a MAGA hat?
In short, what I'm asking in an increasingly desperate fashion is--what would it take to unify us? What would it take for us to finally, finally agree that there is such a thing as scientific truth, and such a thing as universal human ethics, and that despite our ideological differences, we still are one species, and that your fellow human has dignity and value? Is there ANYTHING that could do it?
Can we humans transcend our tribal beginnings and stop looking at one another as the enemy? Can we look across the ocean, or the mountain, or the plains, and see not a competitor but a friend?
Now we are engaged in a great pandemic, testing whether this nation--and this world--can endure. Not endure as Lincoln meant, but endure as one people. Maybe we never were. Maybe the talk of how it was better in the old times is just that--talk. Maybe tribalism can't be bred out of us, not even in the face of a global pandemic. Maybe we're not better than this, and maybe we're still just animals in fancy clothes.
But I have to believe we can see what's important. We should always have been able to see it, but if it takes a drastic and horrible spread of disease, then maybe that's what we gain at the end of all this. Please, if you're reading--realize that there is so much more that unites us than that which divides us. Realize that the human race can accomplish wonders as soon as it decides to stop fighting itself. And that our nation can pause the bickering and lies and jockeying for political and social advantage just while we deal with this threat. And maybe when it's over we'll realize we never needed to bicker in the first place.
Come on, humanity. We can do this.
Be seeing you!
