What are the priority nuclear targets in any country?

Priority 1: Strategic military installations(missile launch facilities, communications centers, command centers, 5,000 ft or longer runways, etc)

Priority 2: State capitals, major terrestrial transportation junctions (Rivers, canals, interstates, railroads)

Priority 3: Tactical support bases

I've listed these off the top of my head. There are quite a few more in each of the priority lists, help me out and list what I missed.
