First, the President apologizes to every nation that we have ever had contact with, both friendly and less so. That was followed up with the dismantling of the missile shield program designed to protect us and our allies (however few we have left) from attack. Now we tell the world that we will never use the nukes we have, regardless of what our enemies may do to us. In a perfect world our enemies would realize that we are a peaceful nation.
Unfortunately, the enemies of freedom and democracy have been probing our country for weaknesses for 50 years. They occasionally find political will faultering but always know that militarily we are superior. That is the only deterrant we possess. Who honestly believes that our enemies will not exploit our final defense? No wonder No. Korea and Iran laugh when we threaten them with "serious" sanctions.
