President Trump is growing “increasingly frustrated” by the war raging in Ukraine — as officials warn that Vladimir Putin’s call for a three-day cease-fire is nothing but a hollow public relations stunt.

The Kremlin on Monday declared a 72-hour pause in fighting next month to mark the 80th anniversary of the defeat of Nazi Germany.

The temporary truce is set to start at midnight on May 8 and last until the end of May 10, which aligns with Moscow’s Victory Day holiday. 

“Russia believes that the Ukrainian side should follow this example,” the Kremlin said in a statement.

“In case of violations of the cease-fire by the Ukrainian side, the Russian armed forces will give an adequate and efficient response.”

In response, the White House reiterated that a temporary truce was not enough and repeated calls for a permanent end to the fighting.

“The president has made it clear he wants to see a permanent ceasefire first, to stop the killing, stop the bloodshed,” White House press secretary Karoline Leavitt told reporters, adding that Trump is growing “increasingly frustrated” with both Putin and Ukrainian President Volodymyr Zelensky.

There was no immediate response from Ukraine, which had previously agreed to Trump’s proposal for a 30-day cease-fire to negotiate an end to the war. 

Moscow, however, has rejected any form of extended cease-fire, claiming any halt in fighting would only allow the West to revamp Ukraine’s defenses. 

A Russian official also warned that Putin’s three-day May cease-fire is a feckless attempt to shift international perceptions — and to try and pull one over President Trump.

“We are sending a signal to the outside world: we are peace-loving, and they [in Ukraine] are terrorists — referring, for example, to the recent killing of General Moskalik,” the official told The Moscow Times on the condition of anonymity.

“Another intended recipient of this signal is the US president himself: ‘Look, Mr. Trump, we are trying,’” the official added.

Meanwhile, it remains to be seen how next week’s cease-fire would play out, as an Easter Day truce last week still saw heavy fighting along the frontlines, with both sides accusing the other of attacking first. 

The fighting along the frontlines remains intense, with Ukraine firing some 119 drones over the border against Russia’s Bryansk region just before Putin’s announcement Monday morning, according to Moscow’s Defense Ministry. 

With no clear end to the war in sight, US Secretary of State Marco Rubio said Sunday that this week would be “very critical” in the Trump administration’s response to the cease-fire effort. 

“[America needs to] make a determination about whether this is an endeavor that we want to continue to be involved in,” he said on NBC’s “Meet the Press.”

The secretary of state had also spoken with Russian Foreign Minister Sergey Lavrov to discuss the “ prerequisites for starting negotiations,” according to the Kremlin. 

Rubio’s remarks came after Trump , who vowed to end the war during the campaign trail, revealed he had doubts about Putin’s sincerity to end the war following one of the deadliest drone attacks against Kyiv. 

Over the weekend, Trump, Zelensky and French President Emmanuel Macron agreed “to pursue in the coming days the work of convergence” to obtain “a solid cease-fire,” according to a French diplomat. 

The framework allegedly “respects the interest of Ukraine and the Europeans,” with Kyiv previously balking at the possibility of surrendering land to the invading Russians in return for peace. 

Moscow has also claimed it has no interest in giving up the conquered land, much to the headache of American negotiators who have insisted that both sides must be ready to make concessions. 

Along with the cease-fire talks, American and Ukrainian officials are also set to formalize a deal that will grant Washington access to Ukraine’s rare minerals in exchange for continued aid.
