BRUSSELS (Reuters) -U.S. Defense Secretary Pete Hegseth warned Moscow on Wednesday that the United States and its allies would "impose costs on Russia for its continued aggression" if the war in Ukraine does not come to an end.
"If we must take this step, the U.S. War Department stands ready to do our part in ways that only the United States can do," Hegseth said at a meeting of the Ukraine Defence Contact Group of Kyiv's allies at NATO headquarters.
Hegseth did not elaborate. His comments came as U.S. President Donald Trump's administration is considering a request by Ukraine for long-range Tomahawk missiles.
'COME TO THE PEACE TABLE'
"Now is the time to end this tragic war, stop the needless bloodshed, and come to the peace table," Hegseth said.
"This is not a war that started on President Trump's watch, but it will end on his watch."
Hegseth called on NATO allies to increase spending on purchases of U.S. weapons for Ukraine, following a report that highlighted a sharp decline in Western military support for Kyiv in July and August.
"You get peace when you are strong. Not when you use strong words or wag your fingers, you get it when you have strong and real capabilities that adversaries respect," he told reporters at NATO headquarters earlier in the day.
Hegseth urged allies to ramp up investment in the Prioritized Ukraine Requirements List (PURL) programme, which replaced U.S. arms donations to Ukraine and now requires allies to pay for U.S. weapons deliveries.
"Our expectation today is that more countries donate even more, that they purchase even more to provide for Ukraine, to bring that conflict to a peaceful conclusion."
NATO Secretary-General Mark Rutte said he expected further pledges, noting that $2 billion already had been committed through the mechanism.

However, this amount falls short of the $3.5 billion Ukrainian President Volodymyr Zelenskiy had hoped to secure by October.
Sweden, Estonia, and Finland pledged contributions on Wednesday. But bigger powers such as France and Britain have made no such commitments, despite Hegseth urging all of Kyiv's allies to contribute to the PURL programme.
"Now ... is the time for all NATO countries to turn words into action in the form of PURL investments. All countries around this table, no free riders," Hegseth said at the start of the Contact Group meeting.
Ukraine remains heavily reliant on U.S. weapons as it braces for another winter of grinding conflict with Russia, which now holds around 20% of Ukraine more than three-and-a-half years into its full-scale invasion.
The Kiel Institute for the World Economy reported on Tuesday that average monthly military aid to Ukraine fell by 43% in July and August compared with the first half of the year.
According to the institute, most military support now flows through the PURL initiative, which by August had been joined by Belgium, Canada, Denmark, Germany, Latvia, the Netherlands, Norway and Sweden.

NATO, or the North Atlantic Treaty Organization, is a military alliance of countries from North America and Europe, established for mutual defense against aggression.
Military support refers to assistance provided by one country to another, which can include weapons, training, and financial aid to bolster defense capabilities.
Military aid is assistance given to a country to help strengthen its military capabilities, often in the form of equipment, training, or financial resources.
A peace table is a metaphorical or literal setting where conflicting parties negotiate terms to resolve their disputes and achieve peace.
The U.S. plays a significant role in international military support by providing funding, equipment, and strategic guidance to allied nations facing threats.
