He certainly did his best to create havoc in the world.

In May 2002, Bolton gave a speech entitled "Beyond the Axis of Evil" in response to President Bush's State of the Union Address (where Bush characterized Iran, Iraq, and North Korea as part of an "Axis of Evil"). Bolton added three more nations to be grouped with the aforementioned rogue states: Cuba, Libya, and Syria. Bolton said they were all "state sponsors of terrorism that are pursuing or who have the potential to pursue weapons of mass destruction (WMD) or have the capability to do so in violation of their treaty obligations."[69] During his time as Under Secretary of State, Bolton "sought to block, and often succeeded in sabotaging" the negotiations that Secretary of State Colin Powell conducted with North Korea
"Bolton is a foreign policy hawk and is an advocate for regime change in Iran, Syria, Libya, Venezuela, Cuba, Yemen and North Korea.[17][18] He has also repeatedly called for the termination of the Iran nuclear deal. He was an advocate of the Iraq War and continues to support the decision to invade Iraq.[19] He has continuously supported military action and regime change in Syria, Libya, and Iran.[20][19] A Republican, his political views have been described as American nationalist,[21][22] conservative,[23][24][25][26] and neoconservative.[27] Bolton rejects the last term.
Bolton negotiated so-called "Article 98" agreements with countries to prohibit them from turning Americans over to the International Criminal Court, which is not recognized by the U.S.[65][66] Bolton said the decision to pull out of the ICC was the "happiest moment" of his political career to date.
In 2002, Bolton held a speech at the Heritage Foundation where he accused Cuba of having a secret biological weapons program, and of collaborating with Libya and Iran.[51][80][81] Bolton asserted, "The United States believes that Cuba has at least a limited offensive biological warfare research and development effort. Cuba has provided dual-use biotechnology to other rogue states."[82][81] Bolton made the remarks a week before former president Jimmy Carter was scheduled to meet Fidel Castro in Cuba, becoming the first U.S. President since the Cuban Revolution to visit Cuba in an effort to build bridges between the two countries.[81]
The State Department's chief bioweapons analyst refused to approve the accusation made in the speech, telling Bolton that the State Department did not have evidence to substantiate Bolton's accusation.[51][80][83][81] Subsequently, Bolton berated the analyst, unsuccessfully sought to fire him, began to exclude the analyst's supervisor from meetings, and tried to transfer the analyst to a different office.[51][80][81] Bolton was also alleged to have sought to punish other intelligence officers who refused to endorse his claims about Cuba.[84][75][81] Paul Pillar described Bolton's attempts to get the intelligence community to endorse his views as among the most egregious recent instances of "arm-twisting" the intelligence community,[83] while Columbia University international relations scholar Richard K. Betts described the reports about Bolton's pressure as "most blatant top-down pressure on intelligence" in the Bush administration.[85] Bolton claims that the issue was procedural rather than related to the content of his speech and that the officers, who did not work under him, behaved unprofessionally.[80]
In April 2004, Bolton again accused Cuba of being a "terrorist and (biological weapons) threat to the United States."[86] Experts at the time disputed the veracity of Bolton's claims, saying that the evidence in support of the claim was weak.[87] In September 2004 and in the wake of the failure to locate WMDs in Iraq, the Bush administration backed off claims that Cuba had an active biological weapons program.
