Two countries are considering whether to impose tariffs on each other's imports as part of a "trade war." The increase in each country's GDP (measured in billions of dollars) for different combinations of tariffs are shown in the table. If initially Country 1 and Country 2 are not allowed to cooperate, they would arrive at a decision. Will this decision change if the two countries are then allowed to cooperate?
