OP is definitely an indian who is trying to "re-assure" his indian delusions when it comes to Pakistan.
Here's the reality.
Ground Forces:
Pakistan has tremendously powerful, remarkably capable, and one of the best trained ground forces. They are armed with every possible weapon that a ground force can hope for. You name it. Tanks, artillery, MRLs, Mechanized infantry, Mobile Heavy artillery guns, anti-tank weapons, air-to-ground missiles, mines, bulldozers, and ballistic missiles etc.
Pakistani ground forces can easily face indian Ground Forces in deserts and plains. Both ground forces are very equally matched. So the invading side would be at a huge disadvantage.
Air Force:
Pakistan Air Force has hundreds of 4/4.5 generation aircrafts armed with latest, top of the line BVRs. Pakistan Air Force has tons of bombs, smart weapons, targeting PODs and what not. Not to mention network-centric warfare capability and AWACs etc.
Yes, in terms of numbers...India has an edge. Also they have more number of quality planes. But in "defensive" role, PAF can face-off any indian aggression from air and can hold its own. In order to have a decisive edge over adversary, an invading power must have a 1 to 3 ratio advantage. Indian Air Force right now has an advantage of 1 to 1.6...No where near the level required to effectively defeat Pakistan.
Moreover, strategy, pilot training, and experience are other factors to count it.
Naval Forces:
Indian coastline is MASSIVE compared to Pakistan--and so is Indian Navy. But Pakistan Navy has a lethal submarine force that can easily keep indians at bay. Naval Forces of Pakistan need more buildup though and this has been going on as we speak.
And add to all this: The most important deterrent: The Nuclear Strategic Force Command of Pakistan.
Over-all, india is completely check-mated and contained by Pakistan. Territorially and geostrategically, It has no where to expand. No where to go. Just stay where it is.
