Terrorism is one thing. And we have already proven that anyone who attacks America will be found no matter the cost or time. However, an aggressive country is something else entirely.
In this Age, America is seen as a bully and is generally not respected in the eyes of the World. This has lead some of our backyard bullies to up their threats and attempt to instigate a war. North Korea is continually threatening attack to the point of preparing for war themselves.
My proposal is to make them an example to similarly minded countries if they make any hostile acts against America or her Allies. Taunting can be tolerated. Actions can not. If N. Korea attacks, we need to be prepared to see it through to the end. And the American People need to know their Government is behind them.
