I am with you, this ballistic missile threat is serious. The first thing we should do is ensure that our airfields can move, thereby making the targeteer's job infinitely harder.
We should also invest in some form of aircraft that doesn't need a long, thin bit of tarmac, easily identified on Google Earth to operate from.
Next we should invest in an aeroplane that can fight these real baddies but also all the other nations - the ones without this BM capability, but with systems I believe to be called SAMs. Some form of LO should crack it.
If only there were some way of combining the three. Hmmm.
