In addition to securing economic wins, Ambassador Buchan worked to ensure America’s allies, including Spain, increased their NATO contributions. Spain’s annual NATO expenditures rose nearly $3.2 billion during his tenure, to $13.16 billion in 2019. He participated in and led meetings at NATO headquarters in Brussels other military bases in Europe to encourage Spain and other allies to meet their commitment to contribute at least 2 percent of GDP to defense. Ambassador Buchan traveled across Europe with U.S. Permanent Representative to NATO, Kay Bailey Hutchison, and other U.S. Ambassadors to discuss economic, security and NATO-related matters.3

Ambassador Buchan pushed for freedom, democracy, human rights and equality throughout his tenure, speaking out against authoritarian regimes, especially in Venezuela and Cuba. He traveled to Venezuela’s border with Colombia to address the humanitarian crisis caused by Nicolás Maduro and his Cuban benefactor. Ambassador Buchan also met interim Venezuelan President Juan Guaidó in Madrid to reiterate America’s support for the duly elected National Assembly, which Maduro’s government had dissolved. Under Ambassador Buchan’s leadership, the U.S. Embassy in Madrid was able to convince Spanish oil company Repsol to wind down its operations in Venezuela.

In 2019, Ambassador Buchan joined thousands of students from across the world to participate in the March of the Living in Poland. The educational event included a march from Auschwitz to Birkenau to educate students about the horrors of the Holocaust and to honor the victims.4

During his over three years of service, Ambassador Buchan prioritized strengthening the collaboration between Spanish and U.S. law enforcement, resulting in 422 tons of illegal drugs seized and $50 million in illicit funds and assets confiscated since 2016.
