United States President Donald Trump has described Russia as an "aggressor" for the first time since the beginning of the invasion of Ukraine, a significant shift in rhetoric from the President. This statement, reported today, contrasts with his previous approach to the conflict, which has not been officially labeled as a Russian invasion of Ukraine. Meanwhile, Kremlin spokesman Dmitry Peskov reiterated claims that "NATO is at war with Russia," stating that the alliance provides "indirect and direct support to Kyiv." Members of the US Republican Congress are expressing growing impatience with both Russia and President Trump's stance on Ukraine. Senator Thom Tillis commented, "Russia is really playing us like a piano right now," while Senator Joni Ernst stated, "I think it is time to move on Russia sanctions. (…) Putin is playing him (Trump) right now." Congressman Don Bacon criticized the President's approach, saying, "He (Trump) has been weak on Russia. He has been great on Iran, but he has been terrible on Russia." In parallel military developments, Russian forces are employing experiences from the war against Ukraine during the "Zapad-2025" strategic exercise in Belarus. Footage from the exercises shows Russian assault infantry approaching "enemy" positions on light vehicles, including motorbikes, to commence an attack. This exercise follows earlier reports of the Russian army’s Baltic Fleet Navy repelling a simulated enemy landing on the shores of the Kaliningrad region as part of the ZAPAD 2025 exercises between 11:31 AM and 11:46 AM UTC on September 15th, 2025. The ZAPAD 2025 exercises were observed by representatives from approximately 23 states. Earlier on September 15th, 2025, a NATO Boeing P-8A Poseidon aircraft conducted aerial reconnaissance over Romania, focusing on the Crimean direction, originating from NATO Sigonella. Separately, Ukrainian drone manufacturers Vyriy and "Fourth Law" announced the mass production of drones with a new guidance system between 10:31 AM and 10:45 AM UTC. Belarusian Defense Minister Viktor Khrenin had previously commented on American officers observing joint Russian-Belarusian military exercises, stating, "You can look at what interests you." The European Union continues discussions on stricter visa restrictions for Russian citizens and diplomats.
