I am convinced that fighter jets (every flying object) do stall. So from quora, Why don't fighter jets stall?
But most of the fighters have thrust:Weight ratio > 1 which means that they are not following aerodynamics at that time (during vertical climbs). You can consider them to be like rockets with propulsion system. It suggests fighter planes don't follow aerodynamics. That means stall can be prevented using the jet power. So what causes them to stall?
Edit: I realized my question is currently away from singularity. Based on comment, jamesqf, zeus and Robert maybe right. That quora answer might be wrong. It claims that fighter jets don't follow aerodynamics. I mean every flying object do follow it. So my question is if fighter jet has enormous power compared to their weight, will it prevent stall by a bit? My prediction is stall only depends upon AoA. Regardless of airspeed, if AoA exceeds critical angle, stall can't be prevented (even using high thrust propulsion). Only way to prevent stall is to decrease its AoA. Are my claims correct? What if flying object relies on propulsion engine for lift (lot like missile, rocket), they keep flying and nothing hinders their speed?
