Question: What does the name of the topic that Eisenhower didn't discuss during the campaign stand for?

Knowledge 1: Dwight D. Eisenhower
Two controversies during the campaign tested him and his staff, but did not affect the campaign. One involved a report that Nixon had improperly received funds from a secret trust. Nixon spoke out adroitly to avoid potential damage, but the matter permanently alienated the two candidates. The second issue centered on Eisenhower's relented decision to confront the controversial methods of Joseph McCarthy on his home turf in a Wisconsin appearance. Just two weeks prior to the election, Eisenhower vowed to go to Korea and end the war there. He promised to maintain a strong commitment against Communism while avoiding the topic of NATO; finally, he stressed a corruption-free, frugal administration at home. [SEP] Knowledge 2: NATO
The North Atlantic Treaty Organization (NATO / ˈneɪtoʊ /; French: Organisation du Traité de l'Atlantique Nord; OTAN), also called the North Atlantic Alliance, is an intergovernmental military alliance between several North American and European states based on the North Atlantic Treaty that was signed on 4 April 1949.
Knowledge 1: Dwight D. Eisenhower
In the general election, against the advice of his advisors, Eisenhower insisted on campaigning in the South, refusing to surrender the region to the Democratic Party. The campaign strategy, dubbed "K1C2", was to focus on attacking the Truman and Roosevelt administrations on three issues: Korea, Communism and corruption. In an effort to accommodate the right, he stressed that the liberation of Eastern Europe should be by peaceful means only; he also distanced himself from his former boss President Truman.

On 7 April 1963, the country changed its official name to the Socialist Federal Republic of Yugoslavia. Reforms encouraged private enterprise and greatly relaxed restrictions on freedom of speech and religious expression. Tito subsequently went on a tour of the Americas. In Chile, two government ministers resigned over his visit to that country. In the autumn of 1960 Tito met President Dwight D. Eisenhower at the United Nations General Assembly meeting. Tito and Eisenhower discussed a range of issues from arms control to economic development. When Eisenhower remarked that Yugoslavia's neutralism was "neutral on his side", Tito replied that neutralism did not imply passivity but meant "not taking sides".

[SEP] Knowledge 2: The Sun (United Kingdom)
On 7 January 2009, The Sun ran an exclusive front page story claiming that participants in a discussion on Ummah.com, a British Muslim internet forum, had made a "hate hit list" of British Jews to be targeted by extremists over the Gaza War. It was claimed that "Those listed [on the forum] should treat it very seriously. Expect a hate campaign and intimidation by 20 or 30 thugs." The UK magazine Private Eye claimed that Glen Jenvey, a man quoted by The Sun as a terrorism expert, who had been posting to the forum under the pseudonym "Abuislam", was the only forum member promoting a hate campaign while other members promoted peaceful advocacy, such as writing 'polite letters'. The story has since been removed from The Sun's website following complaints to the UK's Press Complaints Commission.
