Oh dear.
Operation Neptune Spear happened in Pakistan, not in Panama. In-fact, Panama was also taught a lesson in 1990.
US retains a
limited presence in Afghanistan just to ensure that Taliban does not achieve upper-hand over Afghan government in the conflict and politically; this is a (political) conflict and not a war for extermination. Since US has invested in Afghanistan over the course of years, it won't let Taliban have its way in the country until it is ready to embrace democratic reforms in Afghanistan just like other political entities.
US doesn't have much to loose in Afghanistan by the way and much of the offense will be coming from air and sea and directed towards centers of power and military targets inside Pakistan.
Now, do you understand how combat aircraft and missiles work?
Target acquisition is necessary and access to radar systems is a must. Unfortunately for us, USAF can not only jam on-board sensors of PAF combat aircraft but do the same to radar installations on the ground (on a mass-scale, mind you). They can also knock-out those satellites in the space that may help Pakistani armed forces in the matters of
target acquisition; they might be already marked as we speak.
Here are some assets that are very good at jamming defenses of an enemy:

US has spent lot of time in Afghanistan and you can expect that they have amassed a great deal of Intel about Pakistani defenses and strategic options over the course of years. You never fight a war without this kind of homework beforehand. US doesn't needs boots on the ground to assess and determine strategic locations; they can acquire necessary information from a wide-range of assets from air and space. Learn more from this link:

Next, you make it sound like as if targeting USN vessels across the breath of Arabian ocean is easy. Bro, ever been to an ocean? Expect USN vessels to be widely dispersed, in motion, and with their countermeasures activated to prevent incoming ballistic missiles and/or cruise missiles from getting them. Not just this, but they would be in action, launching a volley of cruise missiles deep inside Pakistan (hitting important target across the country)
in the darkness of the night. USN can strike at
hundreds of targets across the country in a short span, and at this rate, there won't be much left in Pakistan for offensive purpose.
How many ballistic missiles and/or cruise missiles Pakistan has in its inventory? Not many, I tell you.
Should US ever go
all-out against Pakistan, it is game-over for us.
You have literally no idea how modern wars are fought, complexities involved and limitations of Pakistan in these matters. You watch ballistic missiles being tested on predesignated (stationary) targets and learn about Indo-Pak cross-border firing in LOC and you think that every aspect is being taken care off.
Please tell me! Are we super-humans or exempt from the laws of physics? We will just launch some missiles at the USN vessels across the Arabian sea and they will will not only locate their targets with magic but each will score a hit and sink the vessel. Very simple.
Seriously, this forum needs professionals who know what they are talking about.
