Let There Be Peace! - Pāx sit!

"Pāx sit!" is old Latin for "Let there be peace!"  Many have been thinking that a great war has been overdue for some time—77 years having passed since the last.  My thinking is that the 2020s is not like the 1940s, as people are better educated and there are more communication devices and methods, now.  And with modern Chinese making money and getting richer, they are less motivated to change from the status quo.  Sci-fi writers like the British knighted Arthur C. Clarke and the American mulatto Samuel R. Delany do not write about a great war on this Earth.  Clarke writes about America's tricentennial and more space exploration and colonization.  Delany writes, however, about war in the Solar System when neighbouring planets and moons have been already colonized by humans, and this Earth does become severely affected, as some of its colonies revolt against Terran hegemony.

There are Japanese awaiting a great war, which they think is inevitable, as there are tensions at the micro level, so there would be ensuing tensions at the macro level of the human sphere.  Some Japanese foresee their vindication coming, as some Japanese think that they were severely maltreated in the last war.  There are Japanese anime, like No. 6, depicting post-apocalyptic scenarios.  In No. 6, there would be a few surviving ultramodern city-states.  In the Anglosphere, there is Edgar Pangborn's sci-fi book Davy, which depicts a Medieval-like life in post-apocalyptic times.  The vintage teleseries Buck Rogers in the 25th Century depicts a future after a great war on this Earth.  Isaac Asimov, the Russian-born American Jewish sci-fi author, writes in his Foundation series of a great Terran war as a prelude to exploration and colonization of the galaxy, as it becomes home, a Galactic Empire, to zillions of humans.  Larry Niven, an American Jewish sci-fi author, writes about continuing progress on Terra with ensuing space colonization, but he writes that there would be war with alien species like the Kzinti, cat-like humanoids, maybe metaphoric.  Even in the Star Trek franchise universe, a great Terran war is a prelude to First Contact with extraterrestrials and later great space exploration and colonization.
