“What’s that up in the sky?”
…During a 2009 interview with Charlie Rose and Reagan’s Secretary of State George Shultz, Gorbachev revealed that Reagan asked him point-blank if they could set aside their differences in case the world was invaded by aliens…
As far as we know, aliens never tried to take over the planet during the 1980s, so Reagan and Gorbachev’s informal agreement wasn’t put to the test. But perhaps unsurprisingly for a president whose nuclear deterrent plan was nicknamed “Star Wars,” Reagan was a big science-fiction fan. He had grown up reading Edgar Rice Burroughs’ epic science-fiction novels, whose characters included John Carter of Mars and Tarzan
Please, please, no one ask El Trumpo if he’s ready to defend the world against Alien Invaders? The former head of Israel’s Space Security agency says Trump almost revealed the “truth” when he was in office but the Galactic Federation stopped him.

“…Can we and all nations not live in peace? In our obsession with antagonisms of the moment, we often forget how much unites all the members of humanity. Perhaps we need some outside, universal threat to make us recognize this common bond. I occasionally think how quickly our differences worldwide would vanish if we were facing an alien threat from outside this world. And yet, I ask you, is not an alien force already among us? What could be more alien to the universal aspirations of our peoples than war and the threat of war?”
