Secondly, a nuke exploding into the atmosphere won't start a "Planetary fire". Russia tested a 57 Mt device at 80 km from the ground. it looks like we are still there to speak about it, isn't it? and 80 km is still Inside the atmosphere, while the OBS is probably far outside it (otherwise, it would not be "in orbit").
Finally, the idea is that by creating small size rocks, those would be destroyed while entering atmosphere. I agree that making sure that you have only small size rocks may be more tricky, but there may be ways around that too...
And if yougive it the right angle, you may even manage it so that most if not all of those rocks won't even be able to enter atmosphere and will be brushed aside by it... (without the right entry angle, small objects can't enter atmosphere, if I recall correctly)...
80 km from the ground.
Err, no.
It was air dropped. From a propeller bomber. Admittedly one of the best propeller bombers in the history of the world, but a propeller bomber.
There are Youtube segments of the test.
