Deterrence is actually to cause fear in the imaginary enemy, thereby preventing him from doing things that are not good for himself. However, there are two roots to this fear: first, the opponent must recognize the strength of the deterrent, it is difficult to imagine a weak country can deter the powerful United States. Second, the adversary must also believe that the deterrent will use its strength to achieve its purpose. In other words, the adversary must confirm the intention of the deterrent. If the opponent believes that the deterrent is not truly offensive Intent, so simple to show strength or verbal threat is meaningless. According to this text, is the following statement correct? ['Deterrence achieves the purpose of deterrence by making potential opponents believe in their strength.', 'The purpose of deterrence is to stop and fear the attacks of powerful opponents.', 'The true and clear intentions of the deterrent can bring more fear to the opponent.', 'The key to the success of deterrence lies in the perception of the deterred party.']
