I wish Kerala the best and hope they or any other Indian state suffering from such calamities can minimize human losses.
Having said that, with nearly 27% of Muslim and around 18% of Christian population, with a strong overall left leaning Kerala can be a state we can work on for propaganda purposes,
a) to further the already present South/North divide
b) to show to them that Pakistan is not the villain northern politicians and media make us appear.
If I was at helm of affairs right now, I will at least call upon Pakistani nation (by coming on the prime time tv of course) to pray for the innocent people suffering in Kerala in next Friday prayers. And then ask media to run the prayers in Badshahi, Faisal, Mahabat khan and Tooba mosques in their news bulletins. That will show we care and this can be used by the peace makers in India to show a softer image of Pakistan just like that Jhaphi by Gen Bajwa helped in Indian Punjab.
