The theory of military deterrence was based on a simple psychological truth, that fear of retaliation makes a would-be aggressor nation hesitate before attacking and is often sufficient to deter it altogether from attacking. Clearly, then to maintain military deterrence, a nation would have to believed to have retaliatory power so great that a potential aggressor nation would have reason to think that it could not defend itself against such retaliation.

If the statements above are true, which one of the following can be properly inferred?

(A) A would-be aggressor nation can be deterred from attacking only if it has certain knowledge that it would be destroyed in retaliation by the country it attacks.

(B) A nation will not attack another nation if it believes that its own retaliatory power surpasses that of the other nation.

(C) One nation’s failing to attack another establishes that the nation that fails to attack believes that it could not withstand a retaliatory attack from the other nation.

(D) It is in the interests of a nation that seeks deterrence and has unsurpassed military power to let potential aggressors against it become aware of its power of retaliatory attack.

(E) Maintaining maximum deterrence from aggression by other nations requires that a nation maintain a retaliatory force greater than that of any other nation.

OA soon.

I think option D is out as the question type is inference, hence we need to stick to the boundaries of the question, option D mentions " has unsurpassed military power" thats no where discussed in the argument and is completely out of scope.

IMO its E

OA updated the answer is D. E has 2 issues

E) Maintaining maximum deterrence from aggression by other nations requires that a nation maintain a retaliatory force greater than that of any other nation.

We aren't given any info about the degree of deference. Also, we have been given any other nation in this answer choice - the stimulus says "aggressor or potential aggressor."
