(Feb 26): Ukrainian President Volodymyr Zelenskiy said his country has lost 31,000 soldiers since Russia’s full-scale invasion started two years ago as he stressed that a decision from the US Congress on US$60 billion (RM286.6 billion) in aid was needed within a month.

Zelenskiy said Ukraine has a “clear plan” for 2024, while making a blockbuster claim that parts of its 2023 battle strategy had been leaked to Russia.

With the war now in its third year, Russia has gained fresh momentum, exploiting Kyiv’s deficit of ammunition and shortage of troops. US support, a crucial lifeline, faces formidable obstacles in the Republican-led House of Representatives, even after a joint US$95 billion package for Ukraine, Israel and Taiwan cleared the Senate.

“When we talk about US assistance, we should understand that it’s not financial support, mainly it’s weapons,” Zelenskiy told reporters in Kyiv on Sunday during an extended press conference.

“The Patriot air-defense system costs US$1.5 billion, but you can’t buy it without the US and there are no similar systems in the world. We can find money, but we won’t find such an amount of weapons.”

As military supplies to Ukraine are dwindling, Russian forces scored a symbolic victory this month when Ukraine pulled soldiers out of the embattled eastern city of Avdiivka after months of combat. Kremlin troops are probing Ukrainian defenses elsewhere along the 1,200-kilometre (746-mile) frontline.

The Ukrainian president said that 2024 will determine how the war will end, and called US elections in November a potential tipping point.

“It will be difficult for us in the coming months because there are fluctuations in the US that have an impact on some countries, though the European Union showed it is capable of being a leader with its support,” Zelenskiy said.

Ukraine expects Russia to “prepare counteroffensive actions at the end of May or the beginning of summer,” Zelenskiy said, vowing that his forces would be ready to fight. “The tipping point will be elections in the US, and then we will understand what will happen afterward,” he added.

Zelenskiy said Ukraine needs two or three types of weapons to stop Russia’s offensive and break its defensive lines.

“If Ukraine gets 10 Patriot systems for key industrial centers, if we can use them closer to the battlefield, they won’t be able to advance, we would crush their defensive lines,” he said. “It would radically change the situation.”

The Ukrainian leader said that his government doesn’t have precise data on how many civilians have lost their lives in the past two years because some areas are occupied, though the figure is “tens of thousands killed and murdered.”

While Zelenskiy disclosed the first official figure for military losses in many months, he declined to also pinpoint the number of wounded, saying that would help the Russian military.

The Ukrainian president claimed that some plans for Kyiv’s 2023 counteroffensive in the country’s southeast had been leaked to Russia.

“I will be open with you: our counteroffensive actions in the fall of last year were on the Kremlin’s table before those counteroffensive actions started,” Zelenskiy said, without saying who he thought was behind the leak.
