Protectionism

Consider this: when we want to punish one of our enemies we use trade sanctions (think Cuba, North Korea, Iran). This is a logical way of punishing an enemy. So why do use the same mechanism to "protect American workers" that we use to punish foreign nations?

Economist Henry George said it this way:

What protection teaches us to do to ourselves in times of peace
is what enemies do to us in times of war.
