What many Liberals didn't ask themselves is: "What economic sanctions?" "Were we trading with North Korea in any way to where economic sanctions by us would do anything?" The answers are "none" and "no." The only country who could actually deploy economic sanctions is China who was doing business with North Korea and supplying them with important resources like coal.
Obama did nothing to stop North Korea's progress and in the process did nothing to protect Americans from a new nuclear threat as it was business as usual in North Korea. I just don't get why Liberals give their Party unconditional support when they get intentionally misled by their leadership.
