John Bolton, the former US ambassador to the UN named by President Donald Trump to serve as his new National Security Advisor, does not mince words, said an Agence France Presse report. Here are some of the most notable quotes from the arch conservative who is replacing General H.R. McMaster:North Korea "It is perfectly legitimate for the United States to respond to the current necessity posed by North Koreas nuclear weapons by striking first." - February 28, 2018 op-ed in The Wall Street Journal "We have a very limited amount of time left before #NorthKorea gains deliverable nuclear weapons. Weve got to look at the very unattractive choice of using military force to deny them that capability." - January 10, 2018 tweet on @AmbJohnBoltonIran "The inescapable conclusion is that Iran will not negotiate away its nuclear program. Nor will sanctions block its building a broad and deep weapons infrastructure. The inconvenient truth is that only military action ... can accomplish what is required. Such action should be combined with vigorous American support for Irans opposition, aimed at regime change in Tehran." - March 26, 2015 op-ed piece in The New York TimesThe Iraq War "I still think the decision to overthrow Saddam was correct ... The people who say, Oh things would have been much better if you didnt overthrow Saddam miss the point that todays Middle East does not flow totally and unchangeably from the decision to overthrow Saddam alone." - Interview with the Washington Examiner published May 14, 2015 Russia "There needs to be a strategic response to Russias new nuclear missiles to show our allies in Europe that we will not let #Russia push the US or its allies around." - March 2, 2018 tweet on @AmbJohnBolton "Sanctions on Putin and his inner circle are symbolic but ultimately not effective. If you want to punish a country for behavior you dont accept, you need punishing sanctions that are broad, not targeted, and they need to be enforced." - March 5, 2018 tweet on @AmbJohnBoltonUnited Nations "There is no United Nations. There is an international community that occasionally can be led by the only real power left in the world and thats the United States, when it suits our interests and when we can get others to go along ... The Secretariat Building in New York has 38 stories. If you lost 10 stories today, it wouldnt make a bit of difference. The United Nations is one of the most inefficient inter-governmantal organizations going." - February 3, 1994 speech in New York
