Trump stated that Washington had instructed two nuclear submarines to head to 'appropriate areas' in response to the 'extremely provocative' remarks made by Dmitry Medvedev, Deputy Chairman of the Security Council of the Russian Federation. (Background: Trump threatened Russia: If there is no ceasefire in Ukraine in 50 days, the U.S. will impose 100% 'secondary tariffs'!) (Additional context: Is it for real? Putin suddenly announces a '30-hour Easter ceasefire' in the Ukraine war! Bitcoin breaks $85,000) On August 2, local time, U.S. President Trump posted on his social media platform Truth Social, stating that he had instructed two nuclear submarines to head to 'appropriate areas' in response to the 'extremely provocative' remarks made by Dmitry Medvedev, Deputy Chairman of the Security Council of the Russian Federation: Based on the highly provocative comments made by Dmitry Medvedev, former President of the Russian Federation and current Deputy Chairman of the Security Council, I have ordered two nuclear submarines to be deployed to appropriate areas to prevent these foolish and incendiary remarks from becoming a reality. Words are extremely important and often lead to unintended consequences; I hope this will not become one of those cases. The community's response escalated into nuclear deterrence. The trigger for this incident can be traced back to July 28. At that time, Medvedev warned Trump on X platform, 'Don't forget that Russia has powerful capabilities,' and stated that each ultimatum 'is a step toward war.' Furthermore, Medvedev hinted at the Soviet Union's nuclear retaliation system during the Cold War, known as 'Dead Hand.' Trump is playing the ultimatum game with Russia: 50 days or 10 days... He should remember two things: 1. Russia isn't Israel or even Iran. 2. Each new ultimatum is a threat and a step toward war. Not between Russia and Ukraine, but with his own country. Don't go down the Sleepy Joe road! — Dmitry Medvedev (@MedvedevRussiaE) July 28, 2025. A magnifying glass on the Ukraine war situation. The background of the event cannot be separated from Ukraine. Trump previously issued an ultimatum, demanding that Russian forces ceasefire within two weeks after July 29, or face comprehensive sanctions. In contrast, Medvedev's hardline response can be seen as a direct challenge to the deadline set by Trump. Regarding the Russia-Ukraine war, Trump also commented on Truth Social, saying that he only wants to stop this war: I have just learned that nearly 20,000 Russian soldiers have died in the ridiculous war with Ukraine this month. Since the beginning of this year, Russia has lost 112,500 soldiers. This is a large number of unnecessary deaths! However, Ukraine has also suffered great losses. Since January 1, 2025, approximately 8,000 Ukrainian soldiers have died, not including those missing. Ukrainian civilians have also suffered casualties, but the numbers are lower, as Russian rockets have attacked Kyiv and other regions of Ukraine. This is a war that should never have happened — this is Biden's war, not 'Trump's.' I am just here to see if I can stop this war! The fragile test of global order. As the world's two major nuclear powers, the dialogue between Trump and Medvedev undoubtedly adds a layer of unease to the already tense global political and economic order. Although the outside world generally predicts that the conflict between the two sides is likely to remain at the level of warnings and threats and will not evolve into actual conflict in the short term, the standoff between the U.S. and Russia, along with the subsequent evolution of the Russia-Ukraine war, if it leads to new conflicts, will undoubtedly be a sword hanging over the current stock market and cryptocurrency market.
