The whole thing is rather like a particularly bad soap opera. Neighbours bound together for decades, fight and berate the other in public, even as parts of each remains heavily dependent on the other, and quietly co-operate.
That is Pakistan-Afghanistan relations in recent times, all bad language and barbs on one hand and trading heavily, on the other. As the bad vibes mount, there is a tendency to forget that Pakistan has had virtually controlled Afghanistan for more than thirty years, through every praxis.
