It seems right now our military establishment is fine with off the shelf, now Pakistan have to wait for next phase of shock therapy (US military sanction) to wake up. When last time sanctions blocked our way, we ended up with nuclear program, missile program, Tank production and JFT along with many small things like own shoulder fire anti aircraft missile and anti tank missile which we are upgrading till now.Pakistan is in the same dilemma as Turkey was in; and Turkey has made decision by initiating the indigenous defence industry in land, air, sea, E/W.
Pakistan could keep buying on the shelves of Russia, China, USA etc. with ''conditions'' added in her interests for saving the days; or encounter the time and risk the half money in JVs with Turkey for freedom in her interests for the future to come.
At some point, you will have to make this decision either way; today, tomorrow or decades later. Unfortunate to lose many things till awaring of that point.
