I don't think the nukes will fly over this. Russia has dealt with sanctions forever and the US is STILL buying oil and China is buying way more. NATO also all voted down the no-fly zone and even Biden said no military action. The title of this post is misleading the US and Polans aren't flying jets into Ukraine the US is considering giving them fighter jets. The US and EU have already been giving tons of weapons to Ukraine that are killing Russian soldiers. Russia will take back Ukraine and that will be it for a while, I think. Maybe China invades Taiwan next. I actually thought they would invade Taiwan the second this started.
