Russia’s furious response to the U.S.-Israel strike that killed Iran’s Supreme Leader has intensified global tensions and sharpened scrutiny of President Donald Trump’s trajectory at home and abroad.
A senior ally of Russian President Vladimir Putin issued an extraordinary warning after the strike that resulted in the death of Ayatollah Ali Khamenei, a move that has dramatically escalated tensions across the Middle East. The U.K. Express reported that Dmitry Medvedev, Russia’s former president and current deputy chairman of the Security Council, accused Trump of pushing the world toward catastrophe.
“Has the Third World War already begun, or is the world still not entering it, are we balancing?” Medvedev said. “Formally, no, but if Trump continues his insane course of criminal regime change, it will undoubtedly begin. And any event could trigger it. Any event. This is a war by the US and its allies to maintain global dominance. The pigs don’t want to give up their trough.”
Medvedev added that the strike could carry consequences far beyond Tehran.
“Trump made a grave mistake. With his decision, he put all Americans under potential attack, even though the Iranian regime is not well-liked in neighboring Arab countries,” Medvedev said. “The main thing is that the late Ayatollah was the spiritual father of nearly 300 million Shiites. And now he’s also a martyr. You can fill in the rest yourself. And now there’s no doubt that Iran will redouble its efforts to develop nuclear weapons.”
The joint U.S.-Israel operation on Saturday triggered immediate aftershocks. Israel has continued launching additional strikes in Tehran, fueling fears of a widening regional war. Putin condemned the killing in unusually strong language, calling it “a murder committed in cynical violation of all norms of human morality and international law.”
Medvedev followed with another message on social media.
“The peacekeeper is at it again. The talks with Iran were just a cover. Everyone knew that,” Medvedev wrote. “So, who has more patience to wait for the enemy’s sorry end now? The US is just 249 years old. The Persian Empire was founded over 2,500 years ago. Let’s see what happens in 100 years or so…”
Russian state-aligned voices also escalated their rhetoric. Dimitri Simes, an American political analyst frequently featured in Russian media, argued that Washington’s actions created strategic openings for Moscow.
“Estonia is waging war against us,” Simes said. “I think we should give it some thought that Mr. Trump unwittingly created political and psychological opportunities for us, he untied our hands for our Supreme Commander in chief to do whatever he finds appropriate to do for the nation’s security.”
The international fallout has again defined Trump’s second term by intensifying clashes over executive authority.
In a February 2026 interview on NPR’s Fresh Air, Atlantic writer Robert Kagan warned that the United States may already be approaching authoritarian rule. “I think we’re already well into a dictatorship,” Kagan said, arguing that Trump’s consolidation of federal agencies and efforts to control election structures mark a decisive shift.
Polling suggests those concerns extend well beyond Washington insiders. A Navigator Research survey released in April 2025 found that 63 percent of Americans say Trump believes he is above the law. Majorities of independents and non-MAGA Republicans agreed. The same report found that 65 percent of Americans view Trump’s violation of court rulings as concerning and 60 percent see his comments about pursuing a third term as a threat to democracy.
Legal scholars have documented repeated constitutional disputes. A May 2025 analysis from the Center for American Progress examined executive orders invoking the Alien Enemies Act, targeting law firms, and testing limits on presidential authority. The report’s conclusion was direct. “The short answer is no,” the analysis stated when addressing whether certain presidential actions were constitutional.
In Washington, D.C., where the White House, Supreme Court, and Congress sit within blocks of one another, the constitutional confrontation has caused massive tremors. Federal judges in the District have issued rulings blocking certain executive actions as the Supreme Court continues to face mounting pressure to define the outer limits of presidential authority. Meanwhile, heightened security measures have been visible around federal buildings following the Iran strike, reflecting concerns about potential retaliation in the nation’s capital.
Critics argue that the same pattern visible in domestic disputes is now playing out on the global stage. Kagan warned that unraveling long-standing alliances could dismantle the post-World War II security order. He cautioned that the collapse of that system could return the world to a more volatile era of great power conflict.
Now Moscow’s rhetoric has amplified that warning, noting the strike as the latest step in what it describes as an aggressive campaign of regime change.
“Any event could trigger it,” Medvedev said.
