Ukrainian president Volodymyr Zelenskyy said that the $8billion in military aid from the US will help his country achieve victory against Russia.

He said “We will use this assistance in the most effective and transparent way possible to achieve our main common goal: a victorious Ukraone, a just and lasting peace, and transatlantic security”

Zelesnky met with Joe Biden at the White House on Thursday to present his wartime “victory plan,” after the US president announced the multi billion dollar surge in military aid for Ukraine’s fight against Russia.

France24 reports: Zelensky is looking to shore up support for his war effort at the same time as Biden tries to lock in aid for Ukraine, ahead of the white-knuckle vote pitting Biden’s Vice President Kamala Harris against firebrand Trump.

The Democrat pledged nearly $8 billion in military aid in his announcement on Thursday, including $5.5 billion to be authorized before it expires at the end of the US fiscal year on Monday.

Biden said in a statement that the “surge in security assistance for Ukraine” would “help Ukraine win this war.”

Biden also announced Washington would provide Ukraine with the Joint Standoff Weapon (JSOW) long-range munition and called a summit of allies in Germany in October.

The White House however played down Ukraine’s hopes that Zelensky’s visit would achieve his long-held goal of getting permission to fire long-range Western-made missiles into Russian territory.

“I’m not expecting there to be any new announcements on this particular action or a decision coming out of this meeting,” Press Secretary Karine Jean-Pierre told reporters.

Harris was due to meet Zelensky separately at the White House on Thursday.

Zelensky also visited the US Congress—where his government said he had also presented his victory plan—and gave a defiant address at the UN General Assembly on Wednesday.

‘Greatest salesman on earth’

But Zelensky’s visit has prompted fresh nuclear saber rattling from Moscow, which has repeatedly warned the West against giving Ukraine long-range arms.

President Vladimir Putin on Wednesday announced plans to broaden Moscow’s rules on the use of its atomic weaponry in the event of a “massive” air attack.

US Secretary of State Antony Blinken called the nuclear threat “totally irresponsible” while EU foreign policy spokesman Peter Stano said Putin was making a “gamble with his nuclear arsenal.”

Kyiv faces an increasingly difficult battlefield situation two and a half years into Russia’s invasion, with Russian forces continuing to push into eastern Ukraine.

But the US presidential election means Washington’s support now hangs on the balance—and with Zelensky apparently at odds with Trump and the Republicans.

Trump had also been due to meet Zelensky during his US visit, but their talks now appear to be on ice.

Trump accused Zelensky on the eve of the visit of refusing to strike a deal with Moscow and once again questioned why the United States was giving billions of dollars to Kyiv.

At an election rally on Wednesday, the Republican called the Ukrainian president “probably the greatest salesman on Earth.”
