BigMike, first of all, (EDIT) thank you for calling it a war. The news media at times looks for other words when describing bombs falling. But as Kathy correctly points out, since we are talking tourism here, the question is the larger situation.
Maybe if things go really, really, really well in ending the war, part of the solution will be opening up at least St. Pete. by redifining it as a Level 3. For instance Lviv, Ukraine is a Level 3 destination within a Level 4 country. No visa required, no changing rules, probalby valid medical and travel insurance. "Level 3: Reconsider Travel to the regions of Volyn, Lviv, Zakarpattia, Ivano-Frankivsk, Chernivtsi, Ternopil, Rivne, Khmelnytskyi and Zhytomyr."
For some context, among the Level 3 nations are Guatemala, Nicaragua, Honduras, Egypt, Jamica and Colombia. In this thread the author of the story that was linked got great praise on the forum for their travels with young children through Level 3 countries https://community.ricksteves.com/travel-forum/general-europe/the-joy-of-traveling-to-out-of-the-way-places and we have had recent questions about trips to Egypt so apparently, in general, some in the RS community has no issues with Level 3.
Frank II, you have relatives in russia and Ukraine. One thing that can be dont in preparation for when travel is possible is to start building a network through charity endeavors. There are probably some opportunities in russia, but thats beyond my knowledge. Since you have relatives in Ukraine you might want to look there as a place to start. My preference is anything that help children, but there are all sorts of options. Done right you get to know more about the people and the culture and you build connections that can add to the value and enjoyment of the trip when it does occur. If anyone is interested PM and I can send you some leads.
