Betteridge's law of headlines says: "No".
This entire article is just fifth column "journalism": Defeatism, Ukraine can't win, this war is too expensive for the west, we should invest the money in our societies instead.
It even paints the ongoing ukrainian counter offensive as a failure, even though Ukraine has captured twice the area in 5 days than the Russians did in the last 8 months.
Judging an offensive by it's first days, still deep into a news blackout, only on russian released videos and pictures is just rubbish.
Edit: And coming back to the headline: The US has just announced to replace the destroyed Bradley and Stryker vehicles, the M1 Abrams tanks will arrive in the coming months, F-16 pilots training for Ukrainians has begun, and there's a two-and-a-half-year timeline for the delivery of 6 Patriot systems.
So no, Biden won't abandon Ukraine.
