The war-like situation and how to deal with it?

perhaps) with some tales of experience telling a sorrow tales whereupon one found himself INSIDE the country (with just some pennies in his pocket) where a war-like situation has occurred and the borders were, sort of closed or similar?

Asia and Middle America is a preference.

Try Robert Pelton's The World's Most Dangerous Places and his somewhat bombastic, but occasionally helpful, Come Back Alive.

Thank you.
