Question

why did the united nations update the geneva convention in 1949?
o to help settle disputes between nations before war breaks out
o to promote worldwide peace and international cooperation
o to protect pows and civilians during times of war and conflict
o to prosecute nazis for war crimes against pows and civilians

Explanation:

The 1949 update of the Geneva Convention was mainly to establish more comprehensive and clear - cut rules for the protection of prisoners of war (POWs) and civilians during war and conflict, in response to the atrocities and lack of proper protection in previous wars. It was not primarily about settling pre - war disputes, promoting general peace and cooperation in a broad sense, or specifically prosecuting Nazis (though related to preventing similar atrocities).

Answer:

to protect POWs and civilians during times of war and conflict
