What would you do if your enemy is bent on killing you? The answer should be obvious: You either try to kill him or try to get rid of him by means of another method that you deem fit. Any kind of foreign policy that reflects weakness or apathy might, in the long run, make it easier for those that are waiting to hurt you when you least expect it.
It is well-known that life on earth was structured on a premise by which human beings cannot abide in a peaceful relationship indefinitely, since the beginning of time. War and slavery were always the obstacles that stood in the way of dignity and peace. These two aspects of life on earth continues to linger to this day and age, regardless of how hard we try to achieve a lasting peace, which makes it all the more imperative that our foreign policy should never vacillate but remain firm, while it remains slanted toward an equality of purpose that can help promote a fair exchange of views in order to maintain the status quo.
Our foreign policy must necessarily be attuned to letting those that oppose us know that any kind of threat, direct or indirect, would be met with a justified retaliation. By so doing, we do not merely help ourselves in the process but also our allies that count on our leadership and knowhow.
