Nope. As SA Friday said, one in LEO would send about 1/3 to 1/2 of the continental US back to the 1800s. if a nuke went off in orbit our geo satellites would be the last thing we'd worry about... 60% of all satellites would be instantly turned into space junk, and none of the rest would be able to communicate for a while because of something called scintillation.
