President Miguel Díaz-Canel stood by Cuba's leadership and didn't concede a need for any changes to its government amid President Donald Trump's pressure campaign against the communist country.

In a wide-ranging interview with NBC News' "Meet the Press" moderator Kristen Welker in Havana, Díaz-Canel said there's no "justification for the United States to launch a military aggression against Cuba."

"If that happens, there will be fighting, and there will be a struggle, and we will defend ourselves, and if we need to die, we'll die," he said.
