India also has approximately $300 Billion in Forex Reserves.
Having said that. External debt by itself means nothing, USA has around 95% external debt & Japan has around 180%, same is the case with many other developed countries. But these countries also have big and robust economies a luxury that Pakistan does not have. It is in this context that the situation takes a sinister form. Pakistan's economy is already is a very bad state, afloat only because of foreign aid. What happens when this aid dies down? The Americans cant perennially keep giving aid.
Nothing happens. At the worst of it, Pakistan defaults. I doubt that would happen, but in case it does, Pakistan certainly won't be the only country to have done so given the situation on the ground.
Comparing Pakistan's economy with that of India's is an exercise in futility. Maybe a comparison can be drawn with today's Pakistani economy with that of India's in 1991 when India was close to defaulting (but never did).
The bottom line is that if there isn't enough fiscal space left to cater to even the basics because of loan servicing, then Pakistan may not have a choice but to default. As in the world of cricket, Pakistan has more to clean in house than blame others for the economic misfortune which constantly haunts her.
This is a sad state of affairs but one that most of us Pakistanis are extremely well aware of. Any helping hand is a crutch. Maybe its good for help with the flood relief, but beyond that, no amount of help can rectify Pakistan's economic problems unless and until Pakistani state sweats and toils to fix the problems and set the economy back on track.
