Not to bomb there allies, this only “makes sense” if the country is getting invaded and they want to punish there allies for not defending them. The US cannot be invaded and even if they were they aren’t dependent on there allies to defend them, same with USSR/Russia.

Maybe France or the UK mulled over bombing dc if the Russians invaded but they probably didn’t look too far as that would take away any chance for a d-day 2 that could free them. It also may bring about a counterattack by the US, and France has shown in WWII they would rather surrender to the enemy then see Paris burn.
