You're delusional if you actually believe this. Your background is worth nothing to this topic, so no point bringing it up.
It's not just Afghanistan, the Arabs have relied upon Pakistan countless times to keep up their internal security, and stifle decent, and against foreign military forces; not to mention the massive amount of man power and training Pakistan provides them. The US relies upon Pakistan to keep not only the taliban, but now Daesh in check, so it doesn't spread it's militancy too much.
China considers Pakistan at the center of it's foreign policy when it comes to South Asia, India and the middle east.
Russia has decided to move closer to Pakistan, ignoring Indian protests, and there are rumors abound that Russia is quite interested in CPEC. Russia has also talked to Pakistani officials about TAPI, which runs through Pakistan, as Russia wants to build the Pakistani portion of it.
What you said is simply nonsense, and ignores decades of history, and today's ground reality. India is a great power, and it WILL be a super power one day, but that does NOT mean Pakistan is a weak nation, and brings nothing to the table.
We're already seeing nations circle around Pakistan, considering the growing threat of Daesh in the region. I wouldn't be surprised if India was cooperating with Pakistan to counter such a threat (as they've done briefly in the past).
With admission into SCO, Pakistan's regional and global role is just going to grow further, and that's simply the truth. If Pakistan was not important, China would not insist that Pakistan join, and would not veto Indian demands at the UN.
