Pakistan definitely needs to change its approach. This military expenditure is unsustainable. We all witnessed what happened to Soviet union, 100s of aircrafts, warships, tanks, silos, space shuttles, were left in dust and rust and eventually lost. There is immense cost to maintain whatever equipment we buy,
Pakistan needs 5 - 10 years where focus should only be towards economic revival with minimum defense expenditures. The saved money should be invested on power plants, low cost electricity to export oriented industries.
The non-combat expenditures of Pakistan armed forces must cut down significantly. The non-essential man-power must be cut down as well. A country which is literally drowning in debts should not afford massive 10 to 50-kanal residences of Lt.generals with massive number of helper staff to maintain, cooks, gardeners, drivers, etc. Even armies of most powerful economies will never venture near 'luxuries'. If a military leaders gets use to lavish & materialistic lifestyle then that military is done. It sets a bad example for all the officers down to the lieutenant.
GHQ should also learn that no country has ever succeeded with military junta doing all decisions. They need to see G20 countries and see none of the country is being run by army cheif (directly or indirectly). Any country where a mere 22nd grade officer of one organisation takes matters in his own hands (not just matters but law & constitutions as well)
then that country is doomed.
Army is not designed to run the country. No one in their right mind will ever invest in a country that has no regard of law & constitution. No one will ever think to invest in a country where policies cannot continue and there is no certainty and govts are toppled just because military chief decided to do so. The example which COAS set by dismissing even supreme court's decisions & clear law indications for hold elections is a lesson for any investor that if the basic right to vote can be dismissed then how come they will get any rights at all. So essentially Pakistan has to start from very basics. That uphold law, constitution and civilian supremacy. Everything else will come in its place gradually.
