Not quite as vulnerable anymore.
It was for a time. An EMP would require a nuke at low level.
That is not going to happen. As for all the snowflakes that do not want us to confront NK, when?
We are not under Obama and his idiocy anymore. NK will not advance their program of mass destruction.
It’s easy to blame Obama, but I mainly blame Bush. After 9/11 he promised America he would “never allow the world’s worst regimes to get the world’s deadliest weapons”. Then when NK got them and Iran continued to work towards them he did nothing because he was too busy nation building in Iraq, chasing the delusion that Muslims want liberty and democracy. I knew what to expect from Obama, I expected more from Bush.
