The US State Secretary Antony Blinken and Defense Secretary Lloyd Austin are the highest-level American visit to Ukraine since the Russia-Ukraine conflict started in late February, but analysts said on Monday that the visit may have a very limited impact on the situation on the battlefield. Blinken said Russia is failing in its war aims and Ukraine is succeeding after a secrecy-shrouded visit to Kiev. The US would provide more than $300 million in military financing and approve a $165 million sale of ammunition, according to senior US officials. Austin said that Zelensky's response to the aid was deep appreciation, and he has the mindset that they want to win and we want to help them win. Analysts disagree with the US officials' judgement, and said Ukraine is not showing signs of winning and keeping bleeding, and the territory under control of the Ukrainian government is also shrinking. All of the US moves, including sending diplomats back to Ukraine, are usually for political purposes to prove that Washington has confidence in Kiev, but will do nothing significant to change the situation. How do I safely transport supplies, weapons and ammunition to the Ukrainian forces surrounded by or engaging Russian troops is a big problem, and who are truly benefitting from the US supplies is a question, analysts said. Cui Heng, an expert from the Center for Russian Studies of the East China Normal University, told the Global Times on Monday that the only winner of the Russia-Ukraine conflict is the US. Blinken considers Ukraine a proxy of the US, so he believes that the US victory is Ukraine's victory. Increasing military financing and the sale of ammunition by the US to Ukraine is intended to extend the conflict, not to overturn the situation or end the conflict as soon as possible and has no positive effect on the current situation, Cui noted. Song Zhongping, a Chinese military expert and TV commentator, said corruption in the Ukrainian government and military forces is very severe, so support in terms of money and material can't make a significant change to the ongoing conflict. It is not possible to use money to buy a modernized army. Russia has noticed that the US will only provide weapons or train military personnel outside Ukraine, but won't intervene directly in the situation, Song said. Russia declared the port city of Mariupol liberated in a major battle, with hundreds of Ukrainian troops still surrounded by Russian forces inside a giant steel factory. This is a war that Russia can't lose, so Moscow will try to set an achievable goal and accomplish the mission, Song noted. Some Western media said Moscow will set a deadline on May 9, which will be Victory Day to celebrate the Soviet Union's victory over Nazi Germany. Song disagrees with the idea that setting a deadline is unnecessary for Russia. The director of the Institute of International Affairs at Renmin University of China, Wang Yiwei, told the Global Times on Monday that Russia has seen through the US that Washington won't take any significant actions that could overturn the situation, so it dares to launch the second-phase operation to pursue its goal. Port cities like Odessa and Kherson in the south could be targeted, and Russia could make Ukraine a landlocked country if it can control these cities, and then there could be another round of peace talks, Wang said.
