Sanctions

Sanctions are economic penalties imposed on countries, entities, or individuals to change their behavior. They sit between diplomacy and military force — more coercive than a strongly worded letter, less destructive than war.

Types of Sanctions

• Comprehensive sanctions — broad restrictions on an entire economy (US sanctions on Cuba, Iran). These affect entire populations and are increasingly controversial.
• Targeted/smart sanctions — focused on specific individuals, companies, or sectors. Asset freezes, travel bans, arms embargoes. Designed to hit decision-makers without punishing ordinary citizens.
• Financial sanctions — cutting entities off from the global financial system. The SWIFT banking network disconnection of Russian banks in 2022 was a landmark use.
• Trade sanctions — restrictions on imports/exports. Embargo on Russian oil, restrictions on technology exports to China.
• Secondary sanctions — penalties on third parties who do business with the sanctioned country. The US uses these extensively, leveraging the dollar's dominance.

Do Sanctions Work?

The evidence is mixed. Research suggests sanctions achieve their stated goals only about 30-40% of the time.

Success cases:

• South Africa — international sanctions contributed to ending apartheid (though domestic resistance was the primary driver)
• Iran nuclear deal (2015) — crippling sanctions brought Iran to the negotiating table

Failure cases:

• Cuba — over 60 years of US sanctions haven't changed the regime
• North Korea — heavily sanctioned but continues nuclear development
• Russia (post-2022) — the economy contracted less than expected; adapted by rerouting trade through China, India, Turkey

Problems with sanctions:

• Humanitarian harm — even "targeted" sanctions can devastate civilian populations
• Evasion — states find workarounds through third countries
• Reduced leverage — once maximum sanctions are applied, there's no escalation option short of military force
• De-dollarization — overuse of financial sanctions is pushing countries to develop alternative payment systems
