The US agency tasked with protecting the country from missile attacks is scouting the West Coast for places to deploy new anti-missile defences, two Congressmen said on Saturday, as North Korea's missile tests raise concerns about how the United States would defend itself from an attack.

West Coast defences would likely include Terminal High Altitude Area Defense (THAAD) anti-ballistic missiles, similar to those deployed in South Korea to protect against a potential North Korean attack.
I find this 'scouting' now story barely credible. So the US government has had no contingency plans for homeland defence against a long predicted, possible threat? If true then someone needs to explain.
