real life shtf

[Sunna]

as we all know the shtf for the poor folk of Nepal a few days back , aid comes in from many places around the world , tents , food , ect but I guess nowhere near enough.
if something like that hit us how would we cope with most buildings including , police, army , hospitals , supermarkets , roads , rail, water treatment works almost everything gone over night.

would we recover.

could we recover .

now before somebody spoils this thread before it gets started [I know we don't get big quakes in the uk ] its a get you thinking thread...
