This is a global conflict. The entire world is sweating at the US, because if the world lets this slide, other countries will do the same. Remember that this is somewhat of a prototype for taiwan.
Last week they were talking about having no more money for Ukraine, and this week they are talking about putting US arms dealers directly in contact with Ukraine. This isn't a coincidence.
I'm not worried for Ukraine because the US will absolutely not let Russia win, but the US will drag it on long enough to make astronomical amounts of money and drain Russia completely.
