True if they're just dropping aid packages off with the local authorities to do as they please with, but less true if the NGOs are sending workers to directly distribute aid to the population -- which is what I'm under the impression most NGOs are doing. One of the major reasons for the drop in donors was the Taliban's ban on female NGO workers, which made it more difficult for NGOs to operate effectively in the country; not an issue you'd run in to if you're just dropping off pallets of resources.
