At a minimum, Pakistan should have at least tested improved and enhanced versions of existing missiles. Ideally Pakistan should have tested longer range and preferably newer missiles. None of this hasn't happened after US sanctions by the outgoing Biden administration. Instead India has been busy testing newer missiles with impunity. Probably something papa America was hoping to achieve. Provide India an edge over Pakistan in the missile development domain.
What does this say about missile development in Pakistan? It seems that US sanctions and warnings had the desired effect. Unless Pakistan is covertly developing missiles which it intends to test at a later appropriate time. Another theory would be that the generals don't want to stir the hornet's nest and rather continue on the current trajectory of keeping a low profile. One thing is certain, the generals have decided to apply a balanced and non-aligned policy. This means to do or rather not resort to actions which might anger papa America. I have a hunch that Pakistan won't be testing any missile for a very long time to come.
