Former United Nations ambassador John Bolton is the latest foreign policy hawk to join Donald Trump\u2019s administration, replacing H.R. McMaster as national security adviser. A fierce supporter of the 2003 invasion of Iraq and frequent commentator on Fox News, he\u2019s sparked controversy for his comments on hot spots like Iran and North Korea. Iran nuclear deal "I think it\u2019s a strategic debacle for the United States. You can always tinker around the edges, and the question is whether putting lipstick on a pig is really going to make a difference here. I think the answer to that\u2019s clearly no." - March 20 on Fox News. \u201cThe inconvenient truth is that only military action like Israel\u2019s 1981 attack on Saddam Hussein\u2019s Osirak reactor in Iraq or its 2007 destruction of a Syrian reactor, designed and built by North Korea, can accomplish what is required. Time is terribly short, but a strike can still succeed.\u201d - March 2015 in a New York Times op-ed titled "To Stop Iran\u2019s Bomb, Bomb Iran." North Korea\u2019s weapons program "It is perfectly legitimate for the United States to respond to the current \u2018necessity\u2019 posed by North Korea\u2019s nuclear weapons by striking first." - Feb. 28 in a Wall Street Journal commentary titled "The Legal Case for Striking North Korea First\u201d. He added: \u201cGiven the gaps in U.S. intelligence about North Korea, we should not wait until the very last minute." \u201cHow do you know the North Koreans are lying? Because their lips are moving.\u201d - March 9 on Fox News. "I think the only diplomatic option left is to end the regime in North Korea by effectively having the South take it over." - September 2017 on Fox News. China trade, and Taiwan policy \u201cThey\u2019re stealing our intellectual property. We\u2019re just supposed to sit there, is that the answer? I don\u2019t buy it. I am a free trader but I don\u2019t think that means just getting pounded into the ground when another country does not abide by the commitments it made.\u201d - March 22 on Fox News. \u201cIt is high time to revisit the \u2018one-China policy\u2019 and decide what America thinks it means, 45 years after the Shanghai Communique. Mr. Trump has said the policy is negotiable. Negotiation should not mean Washington gives and Beijing takes." - January 2017 in the Wall Street Journal, where he also advocated for closer military ties with Taiwan. Russia \u201cThe recent Russian presidential election was a chance for #Putin to practice election meddling on his own elections so he can do it better elsewhere. We need a long term strategy to deal with countries like #Russia and #China with long standing rulers.\u201d - March 21 on Twitter. "It\u2019s an act of defiance. It\u2019s saying to London and the other western capitals, \u2018what are you gonna do about it?\u2019 Well, I think there should be a very strong answer to that." - March 15 on Fox News, regarding the poisoning (allegedly by Moscow) in the U.K. of a former Russian spy. Syria, Iraq \u201cRather than striving to recreate the post-World War I map, Washington should recognize the new geopolitics. The best alternative to the Islamic State in northeastern Syria and western Iraq is a new, independent Sunni state.\u201d - November 2015 in a New York Times op-ed, with Bolton referring to such a state as \u201cSunni-stan.\u201d "The U.S. ought to abandon or substantially reduce its military support for Iraq\u2019s current government. Despite retaining a tripartite veneer of Kurds, Sunni Arabs and Shiite Arabs, the capital is dominated by Shiites loyal to Iran." - June 2017 in the Wall Street Journal. Also in the Wall Street Journal, on Syria: \u201cThe Trump administration must take a clear-eyed view of Russia\u2019s intervention. The Syrian mixing bowl is where confrontation between American and Russian forces looms,\u201d he said. \u201cRussia\u2019s interference, particularly its axis with Mr. Assad and Tehran\u2019s mullahs, critically threatens the interests of the U.S., Israel and our Arab friends." Pakistan "Putting too much pressure on Pakistan risks further destabilizing the already volatile country, tipping it into the hands of domestic radical Islamicists, who grow stronger by the day." - August 2017 in the Wall Street Journal, referring to U.S. accusations that Pakistan provides a safe haven for the Afghan Taliban and other groups. Bolton added the U.S. should address the question of China in its South Asia policy, holding Beijing \u201caccountable for the misdeeds that helped create the current strategic dangers."
