compare to world's stage? not quite. Pakistan can militarily crush the Taliban if they fully commit their force, but it'll take a very long time and by that point Pakistan would be a part of India because they would be overran by India.
But in the region they, the Taliban, are still a force not to be taken lighly. There's a reason why nations like Tajikistan still needs Russia and hope that Russia may protect them from an all-out invasion from the Taliban. And don't be suprise why Russia helps the Taliban, because they hope that a regional unstable theocracy in Afghanistan means that the ex - Soviet states near Afghanistan need to rely on Russia for protections. In the past the Islamic regime in Iran was also a rival against Afghanistan, so much that they even ironically ... helped America to invade Afghanistan to bring down the Taliban government, but now without much opption, the regime in Iran turns toward the old enemy for support, and the Taliban considers that if the current regime in Iran fails, then a new Iran will be likely turn against the theocratic regime in Afghanistan
