Same article in the New York Times about the Rapprochement with Cuba. Obama was criticized before for being a warmonger by Bolivia. Although I’ve seen this word before I did not know the exact definition so I looked it up. Warmonger is someone who wants war or stir up war, most likely Bolivia is talking about the United States this way due to all the action taken in the middle east.
