They have no real stake in any decision they make.

And they are not human. Not even a sociopath or psychopathic human. At best they might be able to estimate casualties. LLM's probably can't even reach the logic conclusion of the fictional WOPR Joshua from the movie Wargames [1].

Make LLM's win every game of tic-tac-toe and see if it reaches the same conclusion of WOPR. [1]

Edit: (Answering my own question) From Gemini:

Yes, many LLMs (GPT-4, Claude 3, Llama 3) have been tested on Tic-Tac-Toe, and they generally perform poorly, often playing at or below the level of random chance. While they can understand the rules, they struggle with spatial reasoning, often trying to place a piece in an occupied spot, forgetting to block opponents, or failing to win.

If LLM's can't even figure out tic-tac-toe then surely do not give these things the ability to launch any kind of weapon. Not even rubber bands.
