Kyiv will need much more than the $61bn approved by the US today for a fight that could last years, a military expert has said.
The funding will help triage Ukrainian forces, but success is not guaranteed, according to Bradley Bowman, a defence strategy and policy analyst at the Foundation for the Defence of Democracies.
Realistic goals for the months ahead include avoiding the loss of major cities, slowing Russia's momentum and getting additional weaponry to Kyiv that could help them go on the offensive in 2025.
"In our microwave culture, we tend to want immediate results," Mr Bowman said.
"Sometimes things are just hard and you can't get immediate results. I think Ukrainian success is not guaranteed, but Russian success is if we stop supporting Ukraine."
