U.S. Aid to Ukraine by the Numbers

Since Russia’s February 2022 invasion of Ukraine, the Biden administration has sent more than $75 billion in cash and equipment to the country for its defense. Most of the aid has gone to Ukraine’s military operations, keeping its government running and addressing its humanitarian needs.

Without it, Ukraine would at best struggle to fend off Russia’s army — and might collapse altogether. But now, as Ukraine’s president, Volodymyr Zelensky, visits Washington, the future of U.S. aid is in grave doubt.

President Biden says Ukraine needs a major new infusion of cash and equipment that only Congress can approve. But many Republicans object to pouring more taxpayer dollars into the faraway conflict and are insisting that Mr. Biden make concessions on unrelated U.S. border security issues for their support.

Here’s a look at what aid the United States has sent to Ukraine and the political debate about whether to continue that support.

How much military aid has the U.S. given Ukraine?

The United States has provided more than $44 billion in military assistance for Ukraine since the war started, more than the next four largest contributors — Germany, Britain, Norway and Denmark — combined, according to the Kiel Institute for the World Economy.

Throughout the conflict, the Biden administration has been cautious about providing weapons to Kyiv, fearing it would escalate the conflict with President Vladimir V. Putin of Russia.
