i studied them a bit in my nuclear technologies class. the best thing they have going from what i recall is an intermediate range icbm with a range of about 2000 kilometers.
in other words, if they launched from islamabad, they could barely hit the southern tip of india...maybe not even that.
i knew the pakistanis had skipped the (archaic processing methods)plutonium bomb stage and were working in quite advanced ways with boosted uranium at about 40 kilotons(maybe in the 30s) but i was shocked to find out recently that they might have a hydrogen bomb! i don't know if that's true or not , i'm pretty sure india's tests failed, but...
pu239 and ur235 bombs are ugly at a few dozen kilotons, but a hydrogen bomb at a few dozen megatons is a friggin nightmare hell on earth. seriously - a plutonium bomb make take out downtown manhatten, but a hydrogen bomb would kill people in new jersey and all 5 burroughs too.
scary toejam...this ain't your grandad's nukes, it's a real nightmare. hydrogen bombs work from fusion rather than fission (though fissile materials start the reaction blah blah blah)- they work like a small star for a split second releasing unimaginable energy.
it's squealing stupid to even have them laying around - i've been a proponent of disarmament for ages. they would spell the end of us if enough of em got loose and right now there are literally tens of thousands of em sitting around getting old. i don't think we fully realize what we've been playing with.
the universe is constantly in upheaval with those forces and we have a nice stable oasis on earth - now we want to bring that kind of energy here and put it at the other end of a human finger?
one word: dinosaurs...
