Is sanction a smart way to beat an enemy?

The UN sometimes uses sanctions to force some countries to stop certain actions which could create chaos. These sanctions are sometimes led by some superpowers to weaken their potential threats. However, do the sanctions work? In most cases, the first hit by a sanction is the people who live in the “punished” country. And the gime of the country can use the sanction as a propaganda to increase the hate with the country, which makes foreign countries harder to influence the country’s politics. Moreover, placing an economic sanction could not only shrink the enemy’s country, but also may weaken your own economy as well. Every country has its own comparative advantages, when losing one trading partner due to a sanction, the exports and imports may suffer from it. The sanction may not affect the economy as a whole, but it could potentially directly destroy some businesses which focus on businesses with the sanction-target country. Overall, I think that a sanction cannot destroy one regime, but can make the “enemy” unite and fight back. In addition, economic sanctions damage both sides.
