Lawmakers in both parties see limits on US help for Ukraine

The United States is confronting its own limitations as it works to support Ukraine’s resistance against Russia’s bloody invasion, which is in its second week.

The Biden administration has helped galvanize international unity, enacted rounds of sanctions and is pushing for billions in new aid as it provides both military assistance and help alleviate a growing humanitarian crisis.

But it’s also facing the limits of its power as it tries to balance aiding Ukraine, with Russia’s daily airstrikes dominating the world’s attention, without sparking a broader military conflict that could be catastrophic.
