Well to be honest, there is a point.
What do we supply them with?
Our tanks are being made so slowly that they won't be over in time for our own military.
Our gunship is still in testing phase and has to first complete a massive 180 order by IAF and IAA.
BrahMos is something Afghanistan currently cannot afford to wield in sufficient numbers.
Tejas has become the perennial lost case.
Nuclear missiles are out of question.
Nirbhay is still in testing phase and they will still need to wield enough numbers even if it is cheaper than BrahMos.
We're making good progress in warships
BUT Afghanistan is a landlocked country.

So thanks to the bullshit sarkari regime and the NO-ACCOUNTABILITY-BY SARKARI-EMPLOYEES system, there is nothing we can offer the Afghans.
