KYIV, Ukraine — Ukrainian and Western leaders on Sunday welcomed a desperately needed aid package passed by the U.S. House of Representatives, as the Kremlin warned that passage of the bill would “further ruin” Ukraine and cause more deaths.

Ukrainian commanders and analysts say the long-awaited $61 billion military aid package — including $13.8 billion for Ukraine to buy weapons — will help slow Russia’s incremental advances in the war’s third year — but that more will likely be needed for Kyiv to regain the offensive.

The House swiftly approved $95 billion in foreign aid for Ukraine, Israel and other U.S. allies in a rare Saturday session as Democrats and Republicans banded together after months of hard-right resistance over renewed American support for repelling Russia’s full-scale invasion.

Ukrainian President Volodymyr Zelenskyy, who had warned that his country would lose the war without U.S. funding, said that he was grateful for U.S. lawmaker’ decision.

Speaking on NBC’s “Meet the Press,” Zelenskyy said that the aid package would “send the Kremlin a powerful signal that (Ukraine) will not be the second Afghanistan.”

Zelenskyy said Ukraine would prioritize long-range weapons and air defenses to “break the plans of Russia” in an expected “full-scale offensive,” for which Ukrainian forces are preparing.

The aid package will go to the U.S. Senate, which could pass it as soon as Tuesday. U.S. President Joe Biden has promised to sign it immediately.

It still could take weeks for it to reach the front line, where it is desperately needed.

“With this we can stop (Russian troops) and reduce our losses,” said infantry soldier Oleksandr. He has been fighting around Avdiivka, the city in the Donetsk region that Ukraine lost to Russia in February after months of intense combat.

Ammunition shortages linked to the aid holdup over the past six months have led Ukrainian military commanders to ration shells, a disadvantage that Russia seized on this year — taking the city of Avdiivka and currently inching towards the town of Chasiv Yar, also in Donetsk.

In Kyiv, many welcomed the U.S. vote as a piece of good news after a tough period that has seen Russia grind out gains along the front line, and step up attacks on Ukraine’s energy system and other infrastructure.

“I heard our president officially say that we can lose the war without this help. Thanks very much and yesterday was a great event,” said Kateryna Ruda, 43.

Tatyana Ryavchenuk, the wife of a Ukrainian soldier, noted the need for more weapons, lamenting that soldiers “have nothing to protect us.”

“They need weapons, they need gear, they need it. We always need help. Because without help, our enemy can advance further and can be in the center of our city,” the 26-year-old said.
