It takes significantly lower levels of tech to destroy satellites than it does to design and launch them. The big asymmetry lies in the dependency that the US has on both civilian and military satellites. The existing satellite infrastructure will not be retrofitted with armor or other defenses, so the cost of protection is in the trillions of dollars. Within 10 years all satellites will be armored and look nothing like current-day satellites... or perhaps smaller, more disposable sats will become the norm (like those launched by Planet labs). Ground-based lasers are capable of emitting pulses of energy sufficient to damage or disable many satellites.
