Both of you, as witnesses, have talked about the danger in turning satellites into space junk and the vulnerabilities that creates and the existential threat to life here on earth.
However, the big concern that we've had at this committee is the use of EMP, or electromagnetic pulse, and what that can take out. Definitely there'd be collateral damage to infrastructure of existing nations. I would think for countries like North Korea or Iran, which have limited space capabilities, using an EMP would have little detrimental impact upon their own nations. They would take the calculation that it would be greatly damaging to western democracies.
Is there a way to defend against that, and if so, how?
