We will bring it on buddy.
Good Aerial Defence beats Good Aerial Offensive anyday.
Just ask the Israelis in the opening days of Yom Kippur War, then strong Egyptian Air Defenses stopped the mightiest Air Force in the Middle East.
Pakistan cannot match India, plane for plane. But by investing heavily anti-air defenses, one missile battery is equivalent to one Air Squadron and which will level the playing field and cost India dearly economically.
Don't you remember Six day war , How a small country named Israel Defeated Humiliated Whole "Muslim world" in middle east with the help of Strong air force.
