Secretary of State Dulles wanted Eisenhower to know nuclear weapons were, in essence, no different than other weapons:
THE LEGACY OF HIROSHIMA:
A HALF-CENTURY WITHOUT NUCLEAR WARby Thomas Schelling
EXCERPT...
Nuclear weapons again went unused in the debacle following the entry of Chinese armies into Korea, and were still unused during the bloody war of attrition that accompanied the Panmunjom negotiations, which led to the end of the Korean War. Whether the threat of nuclear weapons influenced the truce negotiations remains unclear. But the ambiguity in the "role" of nuclear weapons became evident at that time, and during the ensuing years they clearly remained a threat and a deterrent.
McGeorge Bundy, one of the architects of United States foreign policy in the Kennedy and Johnson administrations, documented the fascinating story of President Eisenhower and Secretary of State Dulles and nuclear weapons in his book Danger and Survival: Choices About the Bomb in the First Fifty Years. At the National Security Council on February 11, 1953, Dulles discussed "the moral problem in the inhibitions on the use of the A-bomb," and it was his opinion that "we should break down this false distinction." Evidently the secretary believed that the restraint was real even if the distinction was false, and that the restraint was not to be welcomed.
Again, on October 7, 1953, Dulles said, "Somehow or other we must manage to remove the taboo from the use of these weapons." Just a few weeks later the President approved, in a Basic National Security Document, the statement, "In the event of hostilities, the United States will consider nuclear weapons to be as available for use as other munitions." This statement surely has to be read as more rhetorical than factual, even if the National Security Council considered itself to constitute "the United States."
Taboos are not easily dispelled by pronouncing them extinct. Six months later, at a restricted NATO meeting, the United States position was that nuclear weapons "must now be treated as in fact having become conventional." But tacit conventions are sometimes harder to destroy than explicit ones, existing in potentially recalcitrant minds rather than on destructible paper.
According to Bundy, the last public statement in this progress of nuclear weapons toward conventional status occurred during the Quemoy crisis, during which the People’s Republic of China repeatedly launched attacks on the island of Quemoy to regain control from Taiwan and the Nationalist forces of Chiang Kai-shek. On March 12, 1955, Eisenhower said, in answer to a question, "In any combat where these things can be used on strictly military targets and for strictly military purposes, I see no reason why they shouldn't be used just exactly as you would use a bullet or anything else."
Was Eisenhower really ready to use nuclear weapons to defend Quemoy, or Taiwan itself? The conspicuous shipment of nuclear artillery to Taiwan was surely intended as a threat. Bluffing would have been risky from Dulles's point of view, and leaving nuclear weapons unused while the Chinese conquered Taiwan would have engraved the taboo in granite.
At the same time, Quemoy would have appeared to Dulles as a superb opportunity to dispel the taboo. Using short-range nuclear weapons in a purely defensive mode, solely against offensive troops, especially at sea or on beachheads devoid of civilians, might have been something that Eisenhower would have been willing to authorize, and nuclear weapons might have proved that they could be used "just exactly as you would use a bullet or anything else." The Chinese did not offer the opportunity.

These are facts we must keep in mind as our nation continues down the warmaking path of "might makes right." Having the biggest gun may make us feel safe, but it also certainly attracts the criminal element who are out to make a name for themselves. We have to find a better way of defending ourselves.
