WASHINGTON — President Trump spoke Thursday with Russian President Vladimir Putin, but admitted he “didn’t make any progress with him” on ending Moscow’s war on Ukraine.

“It was a pretty long call. We talked about a lot of things, including Iran,” Trump, 79, told reporters as he departed Washington for an evening rally in Iowa.

“We also talked about the war with Ukraine, and I’m not happy about that … I didn’t make any progress with him today at all.”

Trump held the call two days after the US cut off air defense missiles and other weapons to Ukraine, citing low American stockpiles.

“Biden emptied out our whole country giving them weapons, and we have to make sure that we have enough for ourselves,” the president argued.

“We’ve given so many weapons, but we are giving weapons, and we’re working with them and trying to help them.”

The Kremlin said the call lasted nearly an hour and that the men had a “frank and constructive” discussion about Ukraine — as well as the political transition in Syria and the fate of the nuclear program in Iran following US airstrikes last month.

Trump “once again raised the issue of ending the hostilities as soon as possible,” the Russian government said.

“In turn, Vladimir Putin noted that we still continued [sic] the search for a political, negotiated solution to the conflict … He also noted Russia was willing to pursue negotiations.”

Putin added, in Moscow’s telling, that he wanted to address the “root causes” of the war — an apparent reference to Ukraine’s pro-Western government — and that “Russia will not back down from these goals.”

Russia invaded its neighbor in February 2022 after Putin alleged discrimination against ethnic Russians and expressed concern about potential NATO expansion.

Prior conversations between Trump and Putin have been coupled with calls by Trump to Ukrainian President Volodymyr Zelensky in an attempt to broker an end to fighting between the countries.

Those efforts have been frustrated by Russia’s insistence that Ukraine recognize Moscow’s territorial gains during the 40-month-old war — which Kyiv sees as a red line — and abandon any hope of joining the 32-nation NATO alliance.

The White House has not revealed plans for a potential call between Trump and Zelensky.

The Pentagon confirmed Tuesday that it had paused shipments of air defense missiles, precision-guided artillery and other equipment.

The Kremlin readout made no mention of the shipment halt being discussed on the call between Trump and Putin.

Zelensky said in Denmark after meeting with major European Union backers that he hoped to speak to Trump about the weapons’ status “maybe tomorrow, or close days.”

Trump and Putin spoke one week after Trump helped broker a cease-fire between Israel and Iran, days after bombing Tehran’s key nuclear sites June 21.

Trump recently has been pessimistic about solving the Russia-Ukraine conflict – likening the nations to children during a White House visit last month by German Chancellor Friedrich Merz.

“Sometimes you see two young children fighting like crazy,” Trump said. “They hate each other, and they’re fighting in a park, and you try and pull them apart. They don’t want to be pulled. Sometimes you’re better off letting them fight for a while and then pulling them apart.”
