Mexico has emerged as a key fuel supplier to Havana as the United States prepares to seize control of Venezuelan oil and the administration of U.S. President Trump hardens its stance toward Cuba.

Cubans are speculating about whether their government will be the next to fall, with Venezuelan oil imports now in jeopardy.

With widespread power outages, medicine shortages and rising food prices, experts say Cuba’s economy has never been worse, with the crisis coming just as the supply of Venezuelan oil is threatened.

Cubans have lowered flags to mourn 32 officers who died in the weekend strike against the president of Venezuela.

The U.S. striking Venezuela and capturing its leader has practical implications for China, Russia, Iran and Cuba, and it also sends messages to each nation.

The top lawmaker on the House Intelligence Committee believes that the weekend capture of Venezuelan President Nicolás Maduro may have a domino effect in Cuba. Chairman Rick Crawford, R-Ark., called it "the beginning of the end" for the regime there.

President Trump said Cuba is "ready to fall" and threatened U.S. military intervention in Colombia following the U.S. attack in Venezuela.

The U.S. military captures Venezuelan leader Nicolás Maduro, threatening Cuba's economy as the nation loses a key provider of oil supplies for communist country's energy sector.

Cuba confirms 32 intelligence personnel killed in U.S. operation that seized Maduro, exposing extensive Cuban involvement in Venezuela's military systems.

The Trump administration is expressing confidence Cuba will fall, but there are concerns the US doesn’t have a plan.
