If it seems as though the US President is the boss of the whole world, it’s because in many ways, he is. Presidential powers for modern presidents are prodigious. With the power to impose sanctions and tariffs, control the government through executive orders, and order military action, a determined president can create a lot of geopolitical mayhem.
The most remarkable tool to that end is the economic sanction which is a form of punishment designed to destabilize countries America has strategic interest in by crippling their economies. Most sanctions bind American companies from doing business in the target nation. But recently, there has been a new form of sanction, called a secondary sanction, that aims to prevent any country or individual in the world from doing business with our declared enemy.
