Just to prove that their military courts are legit and the teach India that going to ICJ was futile, Paki will concoct a way to grant him a death sentence again.If retrial is there, Pakistan won't subject him to death penalty again amid tensions for sure, I think.
Government saved his life at least. Now, bringing him back is challenge.
But yes, the outcome of the current military tension and the eventual realignment (if any) will have some bearing on what will happen to Kulbhushan.
