Americans believe they face a choice in Ukraine: we can continue to help with weaponry and funding, or we can stop now, slowly dialing back our aid or simply cutting it off.
President Biden has proposed a robust aid package: $64 billion in humanitarian and military assistance.
But many Republicans in Congress are calling for an end to US support.
Others in the foreign policy establishment, Democrats and Republicans alike, now argue that Ukraine should be pressured to give up land for peace.
But few people seem to be thinking through the full consequences if America were to walk away.
What would this mean for Ukraine or US global leadership?
