For the first time since the Cold War, nuclear submarines from the United States and Russia simultaneously "appeared" in Cuba, and U.S. anti-submarine aircraft circled overhead. Earlier, the Russian military sent a fleet of ships to Cuba for a six-day visit, including the nuclear submarine "Kazan" and the missile frigate "Admiral Gorshkov", both of which are recently built combat ships in Russia and have great deterrence. Following closely behind was the U.S. military's Los Angeles-class nuclear submarine, which arrived at Guantanamo Bay, Cuba. In terms of time, the two sides had ample opportunities to "face to face".
However, the Russian-Ukrainian war has lasted for several years and there is no sign of a ceasefire, and the US sanctions are still in full swing. In the already tense world situation, the slightest disturbance is enough to attract attention, and it is incredible that the United States and Russia simultaneously displayed their nuclear submarines in Cuba. Some people believe that the two sides just happened to meet. Because the United States clarified on its website that the itinerary of this nuclear submarine was planned in advance, mainly to visit the US military base near Guantanamo Bay, Cuba and perform related military tasks. On the other hand, Russia also responded to the matter, saying that visiting Cuba was only one of the tasks, because before visiting Cuba, the formation also conducted anti-ship missile tests in the Atlantic, and judging from the hypersonic missiles equipped on these two combat ships, it is also possible to exercise combat capabilities in the distant sea.

In addition, the Cuban Ministry of Foreign Affairs also stated that this visit is conducive to the positive development of Cuba-Russia relations, and that international law is strictly observed during the visit; and Russia also went to Venezuela for its next destination after completing its Cuban trip. From these signs, it can be seen that Russia is not heading for a "confrontation".
Recently, the U.S. Treasury Department passed a resolution to impose sanctions on Russia, with the number of sanctions reaching 300, and the scope of sanctions is very wide, involving science, defense, energy and other aspects. In addition, the G7 also reached a consensus that the interest on the frozen $300 billion of Russian assets will be used to support Ukraine. From these aspects, the United States and Western countries are keeping a close eye on Russia, so it is not ruled out that when the United States discovered that Russia was getting close to Cuba, it suddenly decided to intervene and try to hinder Russia's diplomacy and show its "military muscles" to Russia. Moreover, according to public intelligence, the U.S. Navy had sent anti-submarine patrol aircraft to monitor the Russian fleet in the air long before , so it is very likely that the United States deliberately followed.
On the other hand, although Russia also said that this was just an ordinary routine visit, it is well known that the sanctions imposed by the United States on Russia over the years not only include economic sanctions, but also diplomatic sanctions, which have caused many of Russia's "partners" to defect. Therefore, it is self-evident that Russia took the opportunity of the visit to strengthen its influence. Regarding the hegemonic behavior of the United States. Russia confirmed its position and firmly supported Cuba's just demand for an immediate end to the economic, trade and financial blockade of Cuba by the United States. Cuba once again condemned the increasingly aggressive stance of the US government and NATO, including unilateral sanctions against Russia.
