As Ukraine and Russia exchanged intensifying attacks and maintained a second round of negotiations on Monday, the Trump administration has been remarkably calm, indicating a warned but subtle change in the United States to mediate the conflict.

President Donald Trump did not have an immediate public reaction to the dramatic attacks of Ukraine drones within Russia, just before the Ukrainian and Russian delegations were face to face in Istanbul.

The conversations greatly followed the format established by the Trump administration when representatives of both countries held a meeting in May for the first time from the first months of the war.

The Secretary of State, Marco Rubio, was present for the initial discussions, which the United States quickly canceled as a disappointment because Russia chose to send only a group of work level diplomats to represent their interests at the negotiating table.

But this time, Rubio and other high -ranking Trump administration officials played an even smaller role in conversations and maintained even lower expectations.

According to the State Department, Rubio made a call with Russian Foreign Minister Sergey Lavrov, where “President Trump reiterated to continue direct conversations between Russia and Ukraine to achieve lasting peace.” However, the department pointed out in a reading of the conversation that the call was made at the request of Lavrov.

The second round of negotiations was brief and concluded without any progress.

We disappointed but not surprised: officials

After the wrapped conversations, American officials told ABC News that they were disappointed, but not surprised by the important list of demands that Russia said that it must be satisfied before accepting a 30 -day truce, saying that it included a series of articles, both Ukraine and the vision of the Trump administration and indifferent, which calls it a clear attempt of Moscow to boost significant negotiations.

Even before the last conversations, President Trump’s frustration with the lack of progress towards peace has been built. Officials familiar with their thinking say that while they have lashed out by Ukraine and Russia, it has been increasingly disconnected in recent days.

Trump previously threatened to impose new sanctions on Moscow, but after the second round of conversations concluded on Monday, there were no signs that the administration had taken steps to carry out its threat.

Even when negotiations collide, the caliber of the attacks launched by Russia and Ukraine has intensified.

In an operation coordinated on Sunday, Kyiv reached multiple airfields through Russia with large -scale drone attacks, a surprise attack that was the product of more than a year of planning and made it possible for the undercover positioning of smuggling drones deeply within the Russian territory.

Ukraine has affirmed that more than a third of the strategic fleet of Russian bombers was damaged or destroyed in the attacks. But beyond the coup to the military assets of the Kremlin, the attacks are a symbolic victory for kyiv, which shows that Moscow can still inflict pain despite being overcome and surpassed on the battlefield.

“Those who have been saying that Putin is winning are wrong. The Ukrainians remain their own, despite the fact that the support they have been receiving from the United States and other free nations have been unfortunately insufficient,” said Clifford D. May, the founder and president of the Foundation for the Defense of Democracies.

Pressure on Trump to impose toughest sanctions on Russia

“President Trump wants a stop the fire. That is possible, but only if he does good in his threats to press” devastating “in Putin,” May added. A bipartisan group of senators, led by the Republican of South Carolina, Lindsey Graham, undertakes to boost legislation this week that would slapped 500% of tariffs on any country that bought the energy products of Moscow.

Graham and Connecticut Democrat Richard Blucenthal docked strategy with Ukrainian President Volodymyr Zelenskyy last weekend in kyiv.

But until now, Trump has not taken measures, and Russia continued to inflict pain to Ukraine as well. Earlier on Sunday, Moscow deployed a record of 472 Ida attack drones, as well as several ballistic and cruise missiles against the country.

Moscow has also been optimistic about its position on the battlefield before the warmest months in the south, seeing a wide opportunity to claim an additional Ukrainian territory and a negotiation leverage before seriously following any agreement.

“The public statements of Russian officials continue to demonstrate that Russia maintains broader territorial objectives in Ukraine beyond the four oblasts that Russia has declared illegally annexed,” according to a recent evaluation of the Russian offensive campaign published by the Institute for the Study of War, which also said that Moscow remains selfless “in the Good-Faith negotiations to achieve a diploma To war. “

On Monday, Zelenskyy told the ABC Global Affairs correspondent, Martha Raddatz, that his country would continue to fight Russia during the time the war continues.

“Unless they stop, we will continue,” he said.

“We are looking for very solid steps by President Trump to support the sanctions and force President Putin to stop this war,” Zelenskyy added.

But in the White House on Monday, the press secretary Karoline Leavitt responded to the latest events in the conflict only reiterating Trump’s calls to La Paz.

“Look, the reaction is that this war must come to an end,” he said. “The president wants this war to end at the negotiating table, and made it very clear for both leaders, both public and private.”
