Previously, Zelensky's relationship with Trump had been strained for a long time, but Trump's attitude towards Zelensky has softened recently. The Wall Street Journal mentioned in an article on the 28th that sources close to the White House revealed that in recent weeks, Trump has shown new optimism about Ukraine and Zelensky. These people say Zelensky will fight deep into Russian territory, and his resilience has impressed Trump. For Zelenskiy, this is a major turn of events.

These sources said that Trump is now beginning to appreciate the Ukrainian drone industry, especially Ukraine's ability to resist drone attacks. The United States faces a similar threat in its war against Iran.

In addition, photos released by the United States and Ukraine show that Vice President Vans did not attend. However, Vance again attended the U. S.-Israeli leaders' meeting on the same day.

About the shift in Trump's attitude,Wang Yiwei, Director, Institute of International Affairs, Renmin University of ChinaYu told China News Service on the 30th that there are two main reasons: First, Trump has changed and is no longer what it used to be. He has been won by the American establishment, so he has clashed with Vance on issues involving Iran and Ukraine. Second, the current situation is indeed in Ukraine's favor, and there are signs that Ukraine is about to strike back. At least from the point of view of the European system, they need to increase their support for Ukraine in order to achieve the goal of "harvesting" Russia's last assets.

Other analysts believe that Trump's current diplomatic situation is not smooth, there is no progress in the US-Iran peace talks, and an outstanding diplomatic achievement is urgently needed to stabilize the situation and enhance his reputation. The Russian-Ukrainian issue is itself a global focus; if he can make a difference in mediation, it can become an important diplomatic achievement.

More importantly, the recent combat performance of the Ukrainian military has indeed changed Trump's perspective. In recent days, Ukrainian forces have continued to penetrate into Russian territory, launching raids on energy facilities in Crimea, causing widespread power outages and deploying hundreds of drones to strike the Moscow region. According to White House insiders, Zelenskiy withstood the pressure and pushed the front line deep into Russian territory, showing resilience and combat effectiveness, which gave Trump a new assessment of the situation in Ukraine and prompted him to take a more moderate stance and actively relax bilateral relations.

Other analysts said it was unclear whether Trump's renewed goodwill towards Zelenskiy would last. People close to Trump note that his views sometimes change quickly.

On the other hand, Russia has recently announced military expansion. According to a report in the Russian newspaper Izvestia on the 27th, Putin signed an order on the same day to set up a number of military construction engineering units and increased the total number of Russian armed forces to more than 2.42 million, including 1.535 million soldiers in active service.
