Presidents have always exercised emergency powers, but now thanks to dozens of new laws, regulations, court decisions and executive orders, Barack Obama is the most powerful president in all of U.S. history. Of course the U.S. Constitution does not actually give the president any special powers during a time of national emergency, but over time presidents have decided that they should be able to exercise such powers and the courts have generally agreed with them. During World War II and prior to that, these emergency powers were largely uncodified and were primarily used during times of war. But since World War II things have completely changed, and this has particularly been true since 9/11. Over the past decade or so, a whole host of extraordinary powers have specifically been given to the office of the president, and all that it takes to exercise them is a major “national emergency”. So if we do have a full-blown economic collapse, a historic natural disaster, a significant war or a massive pandemic, Barack Obama could use the emergency powers that he has been given to essentially take authority overeverything.
