That is always being repeated, but I wonder if it still holds up with modern systems like the iron dome, and especially laser weapons that are being tested right now. A combination of pre-emptive strikes on NK's artillery, combined with anti-artillery radars and a laser weapons air defense network could render NK powerless.

Edit: that assumes that SK would be the 'liberator', but chances that it would be China are probably higher.
