250 in two years, you must me joking Pakistan total yearly building capability is not more then 18-24 even if you include china still its not close to 250 in two years.
It doesn't matter if Pakistan updating jets or getting new jets, you should look through Center for strategic studies report on Pak-India Airforce. Just for further information go through Indian Airforce modernization program.
Yeh 2 years we are listening this from 1990's... but realistically it won't be happened in next 10 years.
Oh well... we will wait and see... I am sure Pak will want to improve it... especially now....Coz pakistan know whats about to come (god forbids)....so yh Pak will definately try to get as much as they can....we need them badly!
