You have been nuking inactives on White Giant ... you are hardly at risk of attack from them!
All this achieves is to destroy the population which, if you are going to take and keep, or take and strip the country does you no favours either way. If you have no intention of taking the country, why bother to nuke at all?
As for nukes being a deterrent ... pressing for nukes on the game forum and messaging players directly to ask them to sell you nukes or plutonium, is the quickest way to get unwanted attention. Far from decreasing the risk that you will be attacked, it increases it considerably.
You also need to understand the difference between a nuke defence system (nuclear defense batteries ... no plutonium needed) and a nuclear Offense system (plenty of plutonium needed!). If it is nuclear defense batteries and missiles you need, to PROTECT yourself, then you can buy them on the open market. No need to beg on the forum for people to sell them to you.
Having nuclear weapons is NOT a deterrent. Any player deciding to attack you will have plenty of nuke defenses, and sees no threat at all in you having offensive nukes. Nukes have never won wars on their own.
I suggest you learn the game a bit better and learn to play responsibly.
