How is Barack Obama so powerful?

Answer 1

All presidents are powerful, because they are the leader of one of the most influential countries in the world, the United States. Some presidents use their power more aggressively (or assertively, depending on your point of view), but even the presidents that history considered unsuccessful have still been considered powerful because of being the Commander in Chief and the Chief Executive of the USA. Whether you like him or not, Barack Obama is considered powerful because of the influence that America has in the world, and the fact that he can make decisions about how to use that power.
