Ukrainian officials believe that although Donald Trump forces international efforts to end the battle, the war of attrition with Russia is likely to last for several years.

After an uncertain breakup on Friday between Kiev and Moscow in Istanbul, although the U.S. president’s planned call with Vladimir Putin of Russia and Volodymyr Zelenskyy of Ukraine had no evidence that Moscow is serious about peace.

Comments posted Russia's largest war drone attack, with 273 targeting the central Kiev region, Dnipropetrovsk and Donetsk regions in the eastern part of the country.

A senior Ukrainian official told the Guardian: "The Russians cannot destroy us, we cannot liberate our territory. " Without the United States, there is no way to change the balance. (Over time) it will push the balance toward Russia. We will still be alive, but we will pay a huge price. ”

The remarks come a week later, with senior Russian officials taking the appetite for a prolonged war in the Kremlin and making the greatest demands in exchange for peace. These extend to Ukraine from five regions, including those occupied by unoccupied Russian troops.

During the brief Istanbul talks, Russian negotiator Vladimir Medinsky said his country was ready to continue fighting: "We don't want to fight, but we're ready to fight for a second, two, three years, how long have we been fighting Sweden for 21 years. How long have you been ready to fight?

While some Ukrainian officials believe that there may be more room for flexibility if negotiations are indeed conducted, Ukraine and Moscow are as far away as ever on the most fundamental issues.

"There are some real problems with independence and sovereignty and economic and security ties to Western Europe," the senior official said.

"In other respects, the size of the (Ukrainian) military will be subject to economic reasons. Neutrality (Russian demands) is a question of the framework. But we cannot agree to cancel the connection with the West."

As some Ukrainian politicians publicly say, the reality is that the current arrangement of negotiations, especially about Kiev (especially Zelenskyy), is doing everything to make it manifest in the nature of the President’s experience of the Putin war in order to keep the President lukewarm Trump administration around the President.

Oleksandr Merezhko, a politician of the Zelenskyy party, said recently: "(Zelenskyy) is in a difficult situation because behind him is a man who is suffering."

"We're playing, we're trying to do everything we can because we don't want to lose America's support. We don't want to be accused of it's our fault."

Another problem with the fight against the war is Putin’s recognition that restarting the war after a long ceasefire is more challenging than continuing the current conflict.

For lawyer and former deputy defense secretary Hanna Maliar, one of the main difficulties facing meaningful negotiations is the very differentiation of Trump and Putin in the process, including the latter’s ideological investment in the war myth he prosecuted.

"He will continue to work hard. He has the power. He has the power to continue fighting. His goal is to occupy Ukrainian territory. He is achieving that."

In terms of negotiations, she said Putin and Trump “represent a completely different culture.”

"Putin is a KGB agent. He will never resign, he thinks like an invader," she said. "Trump thinks it's like a business negotiation that benefits everyone in some way. But even if they sit at the dining table, they will never reach a common agreement because Putin thinks only in one direction: war, rockets and missiles."

All of this convinced Moro to breathe-again with many other people in Ukraine-the most likely result was prolonged hostilities. "If you ask about the opportunity, I would say that there is a 90% chance of this war lasting one to two years, especially because the intensity of the fight to become president has increased," she said.

As we all know, the danger is that in the long-grinding war of loss, Ukraine has significantly fewer resources than Russia, Ukraine - without the support of the United States and Europe, facing long-term risks.

"The attributive war is like a plateau, and the end is down." "The decline is a collapse of the front line.

"You can't say when it will happen. But you need to push the future. To prevent us from rationalizing the efforts of war to improve effectiveness."

For some in Ukraine, the best situation in current negotiations may be a ceasefire that can freeze the war on the front line without necessarily solving the problem. While some believe this will inevitably benefit from Russia’s preparation for future hostilities, others believe that Ukraine can also benefit from prolonged pauses, allowing it to reorganize its armed forces, increase weapons production and strengthen frontline defenses.

"We are now chatting after three years and two months of war, which is a huge miracle," the official added. "At the same time, I believe Russia will help us through stupid things."
