The US and Ukraine are spreading fears about Cuban fighters in Russia's war, potentially presaging increased pressure on Cuba. A State Department cable directed diplomats to highlight Cuba's alleged deployment of up to 5,000 fighters to support Russia. This coincided with Russia ratifying a new military cooperation pact with Cuba, sparking speculation about formalizing military recruitment. Some suggest Russia might deploy missiles to Cuba, deterring potential US aggression. However, Cuba might be hesitant to provoke a strong response from the US, especially during Trump's administration. The US could exploit speculation about Russian missiles in Cuba to justify increased pressure on the island. Claims of Cuban fighters supporting Russia, whether true or not, could provide a pretext. Ukraine's fearmongering targets Trump, potentially leading to a more aggressive US policy towards Cuba with possible electoral motivations. Observers should closely monitor US-Cuban relations due to the potential for escalating tensions.
