Neither can India. Nobody is talking about 100% TOT. We take what we can get, other stuff we purchase off the shelf. If nobody gives it to us, we steal it. That is why our projects are more successful than India’s. India wants to reinvent the wheel for all their projects hence they get failures like Arjun, Tejas, INSAS or Sitara trainer. The list is unending. India fails even with JVs and imported components.TOT does not cover all aspects. For example, the major requirement for minesweeper is sensor which requires semiconductor. I don't think anyone has given TOT for semiconductor. Simialrly, fire controls, displays etc also need computers & hence semiconductors.
The TOT is limited and as long as Pakistan can't make semiconductors or other critical technology, it has to import
