"International trade is today affected by a high degree of protectionism. The world Trade Organisation (WTO) has in fact failed to prevent the high level of protectionism practiced by the rich countries especially the United States and China."

1. Why do countries go for protectionism?

2.To what extent do you agree that the WTO has failed in preventing protectionism at the international level? Support your answer with relevant cases and examples.

Can some help in these question and if possible give me in details answers.
