An (non-existent) international institution to analyze and take action is the other part of the puzzle.
That said, one can correlate the passes of imagery satellites (optical, radar) with other spaceborne RF sensors, and sensors on airplanes & drones (optical, radar, RF etc.), and data from implanted sensors on the ground, to construct a real-time view of the battlespace.
The Full Monty of these capabilities, especially data fusion from disparate platforms, would never be released to the world.
Fun fact: US overhead systems (NRO satellites) are sometimes quietly used to aid search & rescue activities. A friend of mine, a USAF E-9 who had been read into many compartments during his career, used to do this with the Coast Guard after he retired from the Air Force. Pretty cool stuff.

Like you mentioned, they do use their capabilities for some things other than just GEOINT:
>In addition to using GEOINT for U.S. military and intelligence efforts, NGA provides assistance during natural and man-made disasters, aids in security planning for major events such as the Olympic Games,[9] disseminates maritime safety information,[10] and gathers data on climate change.[11]
It does make me wonder what the NGA does with a ~5 billion dollar budget then, in my head most it was allocated to new sats. Other than buy approximately 10 3080s I mean ;)
Also, probably going towards buying a lot of third-party commercial data.
