1. Which aircraft of Pakistan can carry such bomb ?
2. Which target in afghanistan require a bomb of this scale ?
3. Can advocates of this bomb ensure that there will be no civilian casualties because of this ? Because you are not a murtad state. You are an islamic state which has been provided proper guidelines for wars by their religion and prophet. You can not kill civilian, you can not kill women, you can not kill children's, you can not destroy crop ,you can not cut their trees, you can not toxicity their water or air.
But if you dont bother about it, then go ahead. But challenge #1 and 2 will still remain. And please, spare me from the "they also dont care about these things when attack us" dialogue. I know. But then dont kill what you become otherwise you will go extinct.
