President Vladimir Putin said in remarks published on Sunday that Russia had sufficient strength and resources to take the war in Ukraine to its logical conclusion, though he hoped that there would be no need to use nuclear weapons.
Putin ordered thousands of Russian troops into Ukraine in February 2022, triggering Europe's biggest ground conflict since World War Two and the largest confrontation between Moscow and the West since the depths of the Cold War.
Hundreds of thousands of soldiers have been killed or injured and US President Donald Trump has repeatedly said he wants to end the "bloodbath" that his administration casts as a proxy war between the United States and Russia.
In a film by state television about Putin's quarter of a century as Russia's paramount leader entitled "Russia, Kremlin, Putin, 25 years", Putin was asked by a reporter about the risk of nuclear escalation from the Ukraine war.
"They wanted to provoke us so that we made mistakes," Putin said. "There has been no need to use those weapons ... and I hope they will not be required."
"We have enough strength and means to bring what was started in 2022 to a logical conclusion with the outcome Russia requires."
Trump has been signalling for weeks that he is frustrated by the failure of Moscow and Kyiv to reach terms to end the war, though the Kremlin has said that the conflict is so complicated that the rapid progress Washington wants is difficult.
Former US President Joe Biden, Western European leaders and Ukraine cast the invasion as an imperial-style land grab and repeatedly vowed to defeat Russian forces, which control about a fifth of Ukraine.
Putin portrays the war as a watershed moment in Moscow's relations with the West, which he says humiliated Russia after the Berlin Wall fell in 1989 by enlarging NATO and encroaching on what he considers Moscow's sphere of influence.
Trump has warned that the conflict could develop into World War Three. Former CIA Director William Burns has said there was a real risk in late 2022 that Russia could use nuclear weapons against Ukraine, an assertion dismissed by Moscow.
