ASKAR - my thinking is the same as yours.

The only possible hope was the military units within Nepal, and possibly the Ghurka regiments in Britain - if the UK mobilized them as quickly as possible.

I think that the closest help could conceivably come from China - but its not clear whether they offered a lot of help, and whether it was accepted.

Otherwise you are 100% correct, with rainfall in the quake zone and nightly temps dropping to 12 deg C - any survivors under the rubble will perish very quickly.

VERY SAD.
