Too many things in the article that can be commented upon, and then multiple opinions, but the last para sums it all:

The time has come for some kind of international convention on the legal framework surrounding the uses of such weapons, which promise to shape the warfare of the future as much as tanks and bombers did during the 20th century.

As long as the first world countries get their seat in this convention and dictations in the paperwork, it is bound to be formed.

mixed feelings to know "while India owns an armed Israeli drone designed to detect and destroy enemy radar, though it does not yet have drones capable of striking other targets".
