unless there are weapons secretly mounted on the sattelite(s) about the worst thing they could do is deorbit the satt(s). makes it expensive or in a couple cases impossible to replace the satt(s) as some of the intel birds are pretty big now and the only way to get them up is the shuttle which isn't flying just now. i suppose they could try dropping a biggish satt on the white house but given the lousy aerodynamics of a satt they'd be doing well to hit the city much less a building in it.

Military satellites main usage is spying. Worst case scenario is probably terorists learning a top secret data that satellite spied on.

1) wipe out enough of the GPS constellation and hand-help GPS no worky, jdam GPS mode no worky, ships at sea revert to inertial and celestial navigation. I wonder if the UAVs have a non-GPS mode to revert to. Manned aircraft would also require old-fashioned navigation procedures. Night missions would become far more difficult. 2) Wacking enough spy satellites could cripple a significant portion of our intelligence gathering. Intelligence would get LESS accurate. Enemies would be emboldened to do things above ground that they have only done underground for decades. Wonder if the liberals even understand the deterent value this has. 3) Wacking enough communications satellites would greatly reduce world wide military communications. UAV operators in california might have to relocate to the sandbox in order to operate UAVs in theatre via line-of-sight commo. Pentagon officers might not be able to micro-manage an op on the ground half a world away - which might benefit the US. Is it possible to dumb all those things down low enough to match the lowest common denomenator necessary for movie success? Might have to add LOTS of t&a. ;)
