"We do not believe that dictators should be invited," White House Press Secretary Karine Jean-Pierre tells reporters after key partner Mexico snubbed a regional summit opening Monday in Los Angeles to protest Washington's exclusion of three far-left countries, Cuba, Nicaragua and Venezuela. Some political experts claimed that "The U.S. is trying to bring back and force the Monroe Doctrine on Latin America. They think Latin America is the backyard of the U.S." Mexican President Andres Manuel Lopez Obrador confirmed that he would not attend the Summit of the Americas and said "We think it's a continuation of the old policy of interventionism, of disrespect for nations and their peoples."
