Since doing Physics at high school (years ago..) and since then, university, I have studied this particular branch of physics in particular... In particular, studying some 4,000 pages of declassified US government documents on the development of such "physics package" based weapons.
Put it this way - in the event of a firs strike, there will be very little in the way of preparation before time zero, and it will simply be a matter of post planning. As JAFO has said, we don't have the resources to do it any other way, and as such, it's a matter of picking up the pieces afterwards.
I know it sounds all doomsday and awful, but it's a realistic assessment. We just have to hope, and have faith that humanity will prevail, and that the "bad guys" (who exactly are they anyway...) don't want to destroy us any more than they want to be destroyed.
World politics is a game of chess, and the concept of MAD (Mutually Assured Destruction) is still very much a reality. There are still a million other factors in a real nuclear war that would make it an un-attractive option for any sane individual.. Nuclear Winter, global food produce devastation, and so on are all real. Who knows..
It would take a true madman to attempt such a feat, but, such is the game of world politics and the concept of fear to motivate people.
The best we can do, is keep on going, and not try to anticipate such things - even if you build a bunker in your backyard - you might be able to survive for what - a month? What are you going to find when you run out of food and fresh air/water, and have to finally open the hatch? It's a fair bet that if you are lucky, radiation would probably consume you within a couple of agonising days, or if you are one of the unlucky ones, you will die of a combination of radiation sickness, lack of nourishment, and/or disease.
Sorry or the negative post, I'm off to kiss the kids goodnight and put them in bed. Let this be a reminder to savour every single day we have.
Cheers,
Citabria
