Looking at this from the outside I can't help but feel Khan is not really thinking through what his actual plan or strategy is. Comparing his speeches now to his speeches just before the election he comes across a lot more emotional and even slightly unhinged at times now.
One moment he talks of storming parliament, the PM's house and holding people by the neck etc and the next moment he talks of 'peaceful struggle', non violence etc. He asks people not to pay taxes yet wants them to pay taxes to the regional government he controls. He claims that his march is peaceful yet adding the caveat that it will only stay peaceful for 2 days after which he won't be able to control what the crowd/his supporters do! He talks of punching people and dragging folks to jail and continuously refers to himself in the third person. It's all just very bizarre and dramatic - in fact it's almost Altaf Hussain esq, all we need now is for Imran to start singing a song. I have no doubt he is a well intentioned man however his discipline, calmness and clear thinking, which helped to make him such a great cricket captain, seems to have now deserted him. If the PM does not resign and Khan's supporters all go home then Khan is going to end up with a lot of egg on his face at the end of this all.
Anyway, I hope the outcome to all of this is a peaceful one.
