PAKISTANI WINDFALL?

I WAS JUST WANDERING IF THE PAKISTANI GOVERNMENT CAME IN TO A WIINDFALL OF SAY ABOUT 3-4 BILLION DOLLARS FROM OTHER ARAB COUNTRIES AND MONEY COLLECTED FROM OWN COUNTRY.

HOW DO YOU THINK THEY SHOULD GO ABOUT ACQUIRING MODERN ARMS AND FROM WHO. SUCH AS ,

FLIGHT REFUELLING TANKERS
AWACS PLANES
TRANSPORT PLANES
NEW FIGHTERJETS, STRIKE AIRCRAFT, LONG RANGE BOMBERS, AIR DEFENCE AND GROUND ATTACK.
ARMED HELICOPTERS.

WHAT ABOUT EQUIPMENT FOR THE NAVY WHAT ABOUT AN OLD AIRCRAFT CARRIER FROM THE UKRAINE OR NEW FRIGATES FROM FRANCE OR CHINA.
