After Cuba was plunged into darkness again, Trump said on Monday he believes hell have the honor of taking Cuba.I mean, whether I free it, take it. I think I could do anything I want with it, he said. Trump has described Cuba as a very weakened nation. The Trump administration is demanding that Cuba release political prisoners and move toward political and economic liberalization in return for a lifting of sanctions. Trump has also raised the possibility of a friendly takeover of Cuba. Critical oil shipments from Venezuela were halted after the U.S. attacked the South American country in early January and arrested its then-president, Nicols Maduro.While Cuba produces 40% of its petroleum and has been generating its own power, it hasnt been sufficient to meet demand as its electric grid continues to crumble. Cubas Ministry of Energy and Mines said on X that the island had restored the electrical system in the western town of Pinar del Rio and the southeastern province of Holguin and that some microsystems were beginning to operate in various territories.State-owned media reported that by late Monday power had been restored to 5% of residents in the capital, Havana, representing some 42,000 customers. The citys residents are concerned about food spoiling and simply trying to maneuver in homes with no lighting. The power outages are driving me crazy, said 48-year-old Dalba Obiedo. Last night I fell down a 27-step staircase. Now I have to have surgery on my jaw. I fell because the lights went out.The Ministry of Energy and Mines said earlier that there had been a complete disconnection of the countrys electrical system, noting there were no failures in the units that were operating when the grid collapsed. Lzaro Guerra, the ministrys electricity director, told state media on Monday that crews were trying to restart several thermoelectric plants, which are key to restoring power.Havana resident Toms David Velzquez Felipe, 61, said the relentless outages make him think that Cubans who can should just pack up and leave the island. What little we have to eat spoils, he said. Our people are too old to keep suffering.___Follow APs coverage of Latin America and the Caribbean at https://apnews.com/hub/latin-america
