The most effective way of tackling suffering of people and avoiding refugee problem in any country from aggression of other countries is to give them power to defend themselves and stop others making them refugee. That would be humanitarian thing to do too.
The best arsenal for modern defence and for guerrilla warfare (to defend own country) is to have latest hand held IR-SAM missiles. American supplied stinger missiles in Afghan war that devastated Russian ability to control Afghan sky. When USA attacked Afghanistan, the biggest threat they were worried about was from any leftover stinger missiles.
Pakistan has developed a more effective hand held IR Unza Mk-III surface to air missiles then hand held IR American Stinger surface to air missiles. *.
It is best that Pakistan should start selling Unza III missiles to Iran, Lebanon, Syria or any country in that region (or friendly countries anywhere) that may have interest and want to buy them. This would reduce the cost of manufacturing these missiles (due to increase in their manufacturing quantity) and would bring highly needed foreign exchange earnings to Pakistan that country needs to enhance their defensive ability further.
It would also neutralize Air force superiority of any country in that region, reducing refugee problems and atrocities on civilians (that should not happen in the first place).
I believe that if Pakistan effectively markets such missiles (Unza III is a defensive weapon and all countries should have right to keep as many as they want), Pakistan might be able to sell 5000 to 10,000 of them easily, making Pakistan earn huge foreign exchange. Pakistan should also try to sell other defensive weapons to the region too, that would devastate any aggressors in the area.
[An old article on Unza-III below from an Indian source says that it has an effective range of 7 to 9 Km. What I know, it has range of around 15 Km].

**Pak **to test fire advanced missile in Sept
ISLAMABAD, Aug 30 (PTI) — Pakistan has reportedly developed an advanced version of its surface-to-air “Unza” missile, with which it had claimed to have downed an Indian MIG fighter in the recent Kargil conflict, and proposes to testfire it in September.
"Unza-III, latest in the Unza series of surface-to-air missiles with an extended range than its predecessor, will be tested sometime in September, " the Internews private news agency reported quoting defence officials.
“The missile has an active seven-kilometre range, which can be extended upto nine km,” an official was quoted as saying. Pakistani already possesses the Unza-I with a range of four and a half km and the Unza-II with a range of five km.
The official said preparations were underway at the country’s premier nuclear institution, the Kahuta Research Laboratory (KRL) headed by Abdul Qadeer Khan for the test flight of the missile.
“The decision over serial production of Unza-III will be taken after its satisfactory test.”
Defence officials claimed Pakistan had used Unza-II to shoot down the MIG-21 aircraft of Sq Ldr Ajay Ahuja on May 27 over the Kargil peaks.*
