If no trade in the world what happend among the country

Answer: The country would start to fall, but then would attempt to make, grow, and produce all of their own goods.

Explanation:

If all of a sudden all of the trade in the world stopped there would be so many items lost due to this seeing as we rely on other stations around the world. If the trade just stopped the governement would have to rationalize the food, and oil usage until they could correctly make and drill all the products for themselves.
