The Pentagon said the US military carried out a deadly strike on a boat carrying illegal drugs in the Eastern Pacific. Four men died in the attack, which happened in international waters. The US Southern Command released a video showing a big explosion hitting the boat and flames rising. The strike was ordered by Defense Secretary Pete Hegseth. The military calls the attack a fight against a "Designated Terrorist Organization" moving along a known drug route. This strike is the 22nd since the campaign began in September. At least 87 people have died in similar attacks on boats in the Caribbean Sea and Eastern Pacific. Questions are rising about the legality of these strikes. Earlier attacks killed survivors who were clinging to wreckage. Hegseth has faced criticism after reports said he told the military to "kill them all." A Democrat introduced impeachment articles against Hegseth, citing this and other issues, though success is unlikely. A US admiral said there was no order to kill everyone on the first boat. But Democrat Jim Himes called the footage "one of the most troubling things I’ve seen in my time in public service." He described two survivors in clear distress after their boat was destroyed. Republican Senator Tom Cotton disagreed, saying the survivors were trying to return to fight and nearby "narco-terrorists" might rescue them. Former Pentagon lawyer Ryan Goodman rejected Cotton’s view, saying the survivors showed no sign of active combat. The US government says it is at war with drug traffickers and the strikes are legal under war rules. But most legal experts disagree. Rebecca Ingber, a law professor, said it is illegal to kill people who are incapacitated or shipwrecked. "It is manifestly unlawful to kill someone who’s been shipwrecked," she said.
