Answer:
Israel (wrong)
Israel is one of the least self sufficient countries. It has no oil deposits. It gets most of its water shipped or piped in from neighboring countries, and its agriculture is not enough to sustain its population.
Finland, Denmark, Norway, and Sweden are the most self sufficient. They get most of their oil from the Russian Federation and not the Arab states, but they also have made major strides in alternative energy and many of the populace ride bicycles as a means of transportation.
They have been surviving on their own means for many years until recently, but they could easily return to surviving on their own production without very much trade.
Their population levels are fairly stable and constant, and their agriculture and livestock could sustain them. They also have a diet that consists of a fair amount of fish, and all four countries are known for their fishing industries.
Iceland and Greenland are also fairly high up in self sufficiency.
