While it’s not uncommon for a country’s future to be decided by politicians, a nation’s very existence hinging on a vote 5,000 miles away is as extraordinary as it sounds.

For Ukraine, the six-month wait for this military package has been as costly as it has been frustrating.

Dwindling ammunition has cost it lives and territory.

In this period of rare boosts for Kyiv, this was a biggie – the arrival of American weaponry will allow its beleaguered troops to do more than hang on. But it’s no silver bullet.

So, what is the package going to do? It is likely to include air defence systems, mid to long-range missiles and artillery shells. Ukraine’s recent lack of them has led to Russian forces capturing hundreds more square kilometres of territory.

When the aid arrives, Ukraine can potentially challenge Russia’s air superiority, frustrate their supply lines and slow advancing troops.

When I was in the Donetsk region last month, soldiers said most of the artillery rumbles were coming from the Russian side. Cities like Kostyantynivka and Kramatorsk were bracing for what might be coming. This aid might save those cities.

It won’t give Ukraine the instant means to start liberating territory and force Russia back – but it gives a window for that to happen in the future.

The consensus in Kyiv and Washington is that without this American help, Ukraine would lose.

On a miserable Sunday morning, the warmth of the Kyiv metro will always beat the wet streets above. It’s where we meet Maxym, who’s pleased with the US aid finally being approved.

“I’m really happy about it,” he says. “I’m just a bit disappointed it took so long. Anyways, it’s better late than never.”

Maxym is frustrated by the growing debate over whether Ukraine should negotiate peace with Russia at the expense of territory.

“Russia doesn’t want to negotiate,” he explains. “They don’t want this middle ground that Europe and the US think will end this war. They want it all.”

She then becomes emotional. “It’s impossible. We really want help, for our children to survive, so we wait.” She nods towards her son.

The past six months have not only revealed Russia’s dominance, but Europe’s inability to provide the same level of support as the US.

“We need to think about the hypothetical eventuality the next package of US aid might not pass,” says Mykola Bieleskov, a research fellow at the Ukrainian National Institute for Strategic Studies.

Despite the return of western unity behind it, the issue for Ukraine has always been the time it takes for help to arrive.

Russian President Vladimir Putin certainly doesn’t have to negotiate as many political hurdles when it comes to military spending.

The challenge for President Zelensky now is keeping the politics separate to the fighting. He’ll be under pressure to make this latest American offering count.
