Pax / Astra series

I am reading Andre Norton's Pax / Astra series.  This series contains 2 novels, written in the 1950's.  The first is The Stars Are Ours and the second one is Star Born.  Descriptions and links are below.  One thing which came to mind is how events in the Star Born novel compares to our involvement with questionable leaders and factions in other countries.  Afghanistan in particular comes to mind.  The novel involves Earth people who go to a planet which is inhabited by multiple intelligent species.  The Earth people initially side with one group who turn out to be bad people.

The Stars Are Ours
Earth in 2500AD is no place for a young man with a dream of freedom. And Dard Nordisis worse off than most. His brother was killed for covert activities as a Free Scientist in a world where science is outlawed and blamed for all evils. Now Dard and his niece are hunted and trying to find his brother's friends before their enemies find them and execute them as well. The stakes are high-- he can be shot down and killed like his brother or escape to the stars in a spaceship that the Free Scientists have built in secret!

Star Born
When Raf Kurbi's spaceship from Earth burst into unexplored skies of the far planet Astra, it was made welcome by the natives of a once-mighty metropolis. But Kurbi was unaware of three vital things: (1) that Astra already harbored an Earth colony - descended from refugees from the world of the previous century; (2) that these men and women were facing the greatest danger of their existence from a new outburst of the inhuman fiends who had once tyrannized Astra; and (3) that the natives who were buying Kurbi's science know-how were those very fiends - and their intentions were implacably deadly for all humans, whether Earth born or star born! Much of the planet's hopes lie with young Dalgard Nordis and his companion, Sssuri, a telepathic native of this alien world. If they fail, their planet will be subjugated and enslaved by that inhuman race.
