U.S. presidential hopeful Donald Trump has repeated his earlier criticism of the NATO alliance, saying that the 28-member bloc is "obsolete."
Trump, who is the frontrunner in the race for the Republican Party's nomination for the November 8 presidential election, said in Wisconsin on April 2 that other NATO members are "not paying their fair share."
"Either they pay up, including for past deficiencies, or they have to get out," Trump said. "And if it breaks up NATO, it breaks up NATO."
The real-estate mogul also said Saudi Arabia is "not paying us a fair price" for U.S. protection and military support.
Although Trump's earlier criticism of the NATO alliance provoked concern both in the United States and around the world, Trump insisted in Wisconsin that many experts who had studied NATO "for 30 years" were beginning to agree with him. He did not specify who he had in mind.
