You are very generous with my tax dollars and the population of this former Soviet state.
Its a lot less about tax dollars, but stuff we have already paid for. Btw, I am a tax payer too.
And that stuff in the main was made, long ago, to deal with this situation, not some hypothetical.
If you are truly concerned about your tax dollars then there is a vast range of madness to deal with that is several orders of magnitude greater than aid to Ukraine.
