Sanctions or no sanctions? Effectiveness and deterrence.
There is a tired debate regarding sanctions. Naturally both camps disregard data inconvenient to their stance. Proponents see sanctions as perfect non-violent measures that bring economic hardship to targets. Opponents see it as demonstrably inefficient tools that invariably end up punishing the wrong people. Both sides are simultaneously right and wrong. Cuba is the perfect case study. Years of U.S. sanctions have achieved precisely nothing against the dictators in power.
