Machine translated from german wikipedia (english one is less comprehensive on that but has other details):

New World Pictures acquired the US rights to Nausicaä in 1985. For a children's film release under the title Warriors of the Wind, they shortened the anime by more than 23 minutes, or about a fifth of its total length. The ecological and pacifist message was removed and replaced with a battle of good against evil.11] The names were also changed, with "Princess Sandra" now fighting against evil "Gorgon monsters." This US version also made its way to Europe, where it was released in France by Aprovision as La Princesse des Etoiles and in German by UFA in 1986 as Sternenkrieger, both on VHS.

The Manson cut was derided by Miyazaki, and led to Ghibli's "no cuts" rule for future international releases. It was eventually replaced in circulation by an uncut, redubbed version produced by Walt Disney Pictures in 2005.
