The United States, Who Is Helping Ukraine Fight Russia, Doesn't Want Anyone to Help Russia Fight Ukraine.

 From a "I wanna win" standpoint this makes sense, but at it's core it's a very immature stance: "I can help my friends/allies, but you can't."

But economically, this is what the US is doing: 

The US Treasury Department on Friday took what it called “one of its most significant sanctions actions to date” to crack down on those aiding Moscow’s war against Ukraine, targeting Russia’s metals and mining sector, its financial institutions, its military supply chain and individuals and companies worldwide that are helping Moscow avoid existing sanctions.

These latest actions by the Treasury Department are among a series of new measures announced by the Biden administration Friday that are meant to strengthen Kyiv and deter those providing support to Moscow as the war enters its second year without signs of abating.

Friday’s sweeping actions are meant to fill in gaps in existing sanctions that have been imposed over the past year of the war and are intended to impair “key revenue generating sectors in order to further degrade Russia’s economy and diminish its ability to wage war against Ukraine,” according to a White House fact sheet.

Bad enough that sanctions are economic warfare against the target enemy (in this case Russia) but much like the early sanctions, this is targeted aggression towards other countries, even potentially American and NATO allies (Hello: global economy, anyone?). 

Add this to the number of military missteps the US is making while trying to downplay what's actually going on.
