After finishing 'The Day the Earth Stood Still' somethings been bothering me

Sorry, I paraphrased the threat. Here it is, as it appears on IMDB: The Day the Earth Stood Still (1951) - Quotes - IMDb

(Underlining by me for emphasis.)

Exactly, this isn’t a case of a ‘no guns in town’ sign outside of a Western boomtown, this is the 3 day warning Victorian England gave the Zulu’s to completely disarm.

Really. A lot of human empire’s decended upon the less developed areas of the world, and leveled similar ultimatums.

Victorian England, Imperial Japan, Soviet Union, the USA even.

They all claim that they were doing it for the reasons of self defence, or righting wrongs (Imperial Japan freeing Asia from the yoke of European Colonialism), or uplifting the standard of living for the undeveloped areas, bringing stability, etc.

The only difference here (with Klaatu/Gort) is the level of technological disparity. IMO.

I read a similar story when I was a lad. The world built a computer that would be able to do anything we programmed. To get rid of murder they programmed it to kill anyone that started an action that resulted in the death of another human being. When they turned it on it immediately killed all parents.

I suspect one factor is that, at the time of the movie, no real sense of the size of the galaxy had come anywhere close to being part of popular culture. Till long after Sputnik, it was common for science fiction stories to have people traveling to other star systems by rocket…
In that context, it would not seem odd to think that, once you develop rockets, your armies might turn up anywhere.
Now if the people behind the movie did have any feel for three-dimensional space, it would be true that any society capable of interstellar travel would be very difficult to control. There’s just too many stars. A fleet, or a base, could lurk anywhere.

The general question does turn up in other science fiction. For example, about that time Andre Norton wrote “Star Guard,” the hypothesis of which is that when violent Terrans got out beyond their own planet they met a galactic society which found them unfit for most activities and decreed that until they grew up, Terrans could only go into space as mercenaries.
Some decades later, Niven and Pournelle’s “Mote in God’s Eye” (and associated stories) postulated a Second Galactic Empire, rising out of the ashes of interstellar wars of secession; its prime policy was that since competing interstellar polities are capable of doing far too much damage, there shall be no other polities capable of space travel. Join the Empire, or die.
More recently, James Alan Gardner has a series (starting with “Expendable”) which postulates an unimaginably advanced interstellar League of Peoples which enforces one law: no dangerous non-sentient shall be transported beyond its star system. “Dangerous non-sentient” being defined to include any creature which chooses to kill a sentient being (or to order the death of a sentient). So, on those terms, humans who are willing to live without war are sentient, and are encouraged to colonize the universe; humans who are not willing to live without war are defined as non-sentient dangerous animals, and may not be transported beyond Sol System.
So, the discussion continues …

No, they aren’t.

And why they’re so often wrong.

There is another thread going on right now about the novels of Ian M. Banks, which is relevant here. Banks writes about “The Culture,” a galactic civilization made up of both machine and human intelligences. The machine intelligences are far greater and more powerful than the human ones. The current thinking in SF circles tends to be that once we build an artificial intelligence slightly smarter than we are, we will lose control of our destiny. Looks like that is what happened to Klaatu’s people.

It seems to me that this thread is saying that “The Day the Earth Stood Still” is a great choice for a film to remake. They have a real chance to say something about a more powerful civilization stepping in to reorganize a weaker one. Claiming they are intervening pro-actively to protect themselves from us, despite the fact they are orders of magnitude more powerful? Klaatu should also say that he is taking action to protect us from ourselves. His actions should be definitely shown to kill large numbers of people that oppose him. He should also insist that the peoples of the Earth re-organize our societies along lines that work for his civilization–or else.

Of course, what we are going to get is an action film that makes *I, Robot * look deep and *Starship Troopers * look faithful, but there you go.

The Culture novels are really good. Read them and think about Gort and Klaatu.

I felt Klaatu’s warning was not about our internal violent ways and WMDs; it was the threat of us taking those ways to the stars.

It wasn’t simply “Play by our rules or die” but
“If you come to our field, play by our rules or die; else stay home”.

Yep, O’neal said that the movie to her was a joke. The only reason another culture would be interested in our civilization would be for trade. What that might be, who knows?
Maybe they’ll trade us Gort for Bender.
