Non of that matters when it comes to stand-off weapons that the US has in abundance. The first wave ( not that there is going to be), will be from way out of range. Conventional cruise and anti-radar missiles will simply dilute their capability to negligible levels. Then if they launch their entirely land based air force, they will either be picked off by the US ainti-aircraft capability ( missiles, jets etc)... or they will run out of fuel before they get near a US asset.
They will more likely attach the South Korean forces, but even then, they have no stealth capability, and will be picked off in large numbers.
Just get real Mustafa.
Have to agree most anti aircraft/missile capabilities are over rated and are more for propoganda and keeping the home population reassured. One of the first targets in air military engagment are the radar installations essentially blinding your air defenses and this will still be possible with the bunker buster armaments available to the US. The US may not win a war with North Korea but they wont loss either andthe Korean will definately suffer more colateral damage.
