A very strong decisive factor is: Observe what your ally is trying to invade, and avoid starting capture of any of the same cities yourself. If you do, it is likely said ally will instantly turn against you in order to try taking what you just captured as the AI seems to see you as interference.
A less strong factor I noticed is dependent on how strong you are relative to your ally. If you are far stronger, there are smaller chances that you will be betrayed than in the opposite situation. I assume the AI can assess the risks of starting a war before doing so. Interestingly, this only seems to factor each individual faction, and not the whole alliance group they might be part of, which may sometimes lead to nonsense suicidal war declarations.
As mentioned above, there is also a timer for permanent alliances, it can be configured on the game customization, before starting. Defaults to 120 minutes if I recall correctly. You can lower or rise that on a 0 to 180 minute range. If you want to play with permanent alliances, you can either start with set teams, or just lower that "permanent ally" timer. In both cases, it will result on an unbreakable alliance.
That is why keeping your pops alive and trying to capture new locations intact can be quite powerful to push your development.
As for losing a radar station without being at war, spec ops teams can do that, maybe bomb trucks too but other methods will result in war.
