Pakistan’s longest range missile is the Shaheen-II with a range of 1,400 nautical miles. Our Trident D5 has a range of over 6,000 nautical miles. An Ohio class SSBN could hit Islamabad from port.
Plus our SLBMs and ICBMs (and I suspect our MRBMs) are MIRVed. Also, we have nuclear-tipped cruise missiles, nuclear armed aircraft and things I still can’t speak about. I also suspect that our UAVs are nuclear-capable. No one country or group of countries can stand against us, unless we foolishly disarm ourselves.
