"That's a dangerous statement in itself, but then others around the world might also be inspired to do the same."
In the United States, Monday's inauguration coincided with the federal holiday honoring the assassinated civil rights champion Rev. Martin Luther King Jr., whom Trump mentioned in his speech. Some observers noted the incongruity of Trump's message with King's anti-war ethos.
"How dare Donald Trump invoke Dr. King," pan-African studies professor and Black Lives Matter Los Angeles co-founder Melina Abdullah
fumed on social media. "Trump IS the embodiment of the three evils that MLK warned of: racism, materialism, and militarism."
Indigenous voices reminded listeners that belief in Manifest Destiny fueled genocidal violence against Native Americans.
"Trump is really going after Native Americans with references to Manifest Destiny, the frontier, Wild West, and
erasing Denali's name," attorney Brett Chapman, a direct descendant of the Ponca Cshief White Eagle, said on social media. "This anti-Indigenous inaugural address sounds like one from the 1800s when presidents deployed the U.S. military on Native Americans seeking rights."
In his speech, Trump falsely accused China of "running the Panama Canal," said that Panama—which was last invaded by American forces in 1989—is overcharging U.S. ships to use the crucial waterway, and warned that "we're taking it back."
As angry demonstrators rallied outside the U.S. Embassy in Panama City, right-wing Panamanian President José Raúl Mulino issued a
statement refuting Trump's threats and accusations and declaring that "the canal is and will continue to be Panamanian."
Trump's threat follows his
refusal earlier this month to rule out the use of military force in order to conquer the Panama Canal or Greenland, a territory of NATO ally Denmark.
South American progressives were left stunned by parts of Trump's address.
"In his inauguration speech, Donald Trump made it clear that reality surpasses fiction," Carol Dartora, a leftist lawmaker in the lower chamber of Brazil's National Congress, said in a
video posted online. "Then the U.S. president exuded machismo, imperialism, and xenophobia, especially against immigrants."
Across the Atlantic, former center-right Swedish Prime Minister Carl Bildt
said: "Now we know that President Trump wants to 'expand our territory.' That's a dangerous statement in itself, but then others around the world might also be inspired to do the same. It's a recipe for global instability."
German author, filmmaker, and journalist Annette Dittert
responded to Trump's expansionist pledge with a popular three-letter internet acronym: "'We will become a nation that expands our territory?' WTF?"
