If you were influential in US politics, what would you recommend the US should do in reference to the war in Ukraine?

Let’s pretend you’re influential in US politics and someone would appreciate and actually listen to your opinion regarding the war in Ukraine. What would you recommend the US do? Should the US make and then have to enforce a “no-fly zone” over the Ukraine? Should the US do nothing, militarily? Should there be something else the US can do or should do, in your opinion (the opinion of someone influential whose opinion is valued)?
