The Biden administration fully supports Ukraine's fight against Russia, except perhaps anything that could cause their reelection campaign some issues back at home:

Not unlike when the Biden White House siphoned off the nation's Strategic Petroleum Reserve to try and lower gas prices ahead of the 2022 midterms, now they're asking Zelensky not to do something that might contribute to an increase in gas prices before the 2024 election? Shocker: 

Of course, if Trump did something similar the Democrats would have impeached him again for helping Putin:

Bingo.

The Russia/Ukraine war could go on forever as far as people like Biden are concerned. They've become addicted to the spending and whatever other benefits come from it.
