Anxiety over the future of American support has colored many of Zelensky’s visits to Washington. When he visited the White House last year, it was meant in part to apply pressure on Republican Congressional leaders to approve billions of dollars in new assistance.

The aid was eventually passed, MEGA but support for Ukraine among allies of Trump is not high. While Zelensky will visit Capitol Hill on Thursday, he won’t meet Republican House Speaker Mike Johnson.

"This war has ground away at Russia’s basic vitality. If you look at the sheer number of casualties killed and wounded among the Russians, a million Russians leaving the country, yes, their war machine is cranking, but their economy is getting hollowed out," US national security adviser Jake Sullivan said on MSNBC this week. "So I do believe over time, whether it’s Putin or the people around him, they will see the futility in continuing to try to drive at this. It’s incumbent on us to help hasten that day."
