Can Nukes Start Multiple Wars/Damage Surrounding Units?

I am wishing to take over Hungaria to use as an FOB while taking on other larger forces. Hungaria is entirely surrounded by hostile units with only 6 small provinces remaining. I dont own any provinces bordering theirs but I am within plane and rocket range. My strategy is to Nuke their provinces and drop enough rockets until their forces are depleted then send in my paratroopers to secure it. I am aware that nukes have a large blast radius so my concern is that my nukes might damage the surrounding hostile armies are start numerous wars for which I am not prepared. Is this a viable concern, should I use just rockets and save the nukes? Or am I good to go ahead with my plan? In the close vicinity I currently have 1 nuclear bomber, 6 Nuclear Rockets, 12 Rockets, and 20 paratroopers. I also have my main airforce on station to assist. Hungarian Troops consist mainly of anti air forces and planes. Thanks for the help yall.
