What will the Ukrainian president's visit to Washington this week accomplish?

Ukrainian President Volodymyr Zelensky is meeting with President Biden in Washington this week and addressing a joint session of the US Congress, his first known trip out of the country since the beginning of the Russian invasion last February.

This visit is more than a symbolic one, as bipartisan support for Ukraine has been the key to the more than $60 billion in military and humanitarian assistance the US has provided to Ukraine since the beginning of the war, far more than any other country and a key ingredient in helping the Ukrainians resist the invasion. Zelensky is going to get more commitments from the US this week, including a Patriot missile system to help them shoot down Russian attacks on civilian infrastructure and an additional $45 billion in military and humanitarian aid that is designed to last through at least the end of Q3 next year.
