Can ricardian model explain the phenomenon of trade protection? Why?

Ricardian model can't explain the phenomenon of trade protection. Ricardo advocates free trade and opposes protectionism. His theory of comparative advantage emphasizes that free trade can maximize the benefits of both sides, so his model cannot explain the phenomenon of trade protection.

Ricardian model is a trade theory model put forward by david ricardo, a British classical political economist, which explains the phenomenon of international trade with the differences of labor productivity among countries.

Ricardo's international trade model is one of the simplest trade theory models, and its two core meanings are: the difference of labor productivity plays an important role in international trade; The trade pattern depends on comparative advantage, not absolute advantage.
