Sir six squadrons of PAF fighter jets already station inside and around Karachi. How much more want to place there.Lahore is symbolic but doesn’t stop Pakistan’s war effort from moving forward. Just because PML(N) decided to make Lahore their entire focus doesn’t mean its advanced infrastructure or food scene have actual contributions to ensuring men & material can be thrown into the defense of the country.
Karachi can be bombarded all over but that is where it needs to be protected due to it providing the lifeline to the Sea and the facilities at SITE,KPT and Port Qasim.
Everything you have provided in Lahore’s defense is purely symbolic and nothing more. Lahore can be leveled to the ground but if the port facilities near Karachi(and Gwadar) keep functioning the rest of the country will continue to operate. Lose the ports and then you can happily go to wagah and twist your mooch on a donkey because no fuel is coming in to run your vehicles.
