Classical and Neoclassical trade theory

Classical and Neoclassical trade theory makes the case that free trade can bring a country to an optimum and economically efficient use of its resources; and hence is an optimal trade-policy, if the objective is maximizing long term economic growth.

There are others who argue that the experience of these countries cannot be used to verify or support the argument above. Explain.
