Quotas and tariffs discourage foreign governments from retaliating with quotas and tariffs of their own.

Quotas and tariffs are forms of protectionism that restrict trade and can lead to trade wars between countries. When one country imposes quotas and/or tariffs on imports from another country, it is likely to provoke retaliation from the affected country. This retaliation may come in the form of similar restrictions on imports from the first country, or other forms of economic retaliation. Therefore, instead of discouraging foreign governments from retaliating, quotas and tariffs actually increase the likelihood of retaliation and trade disputes.
