The United States has long been seen as the world’s leading superpower. It is home to the globe’s biggest military and political force – but has many diplomatic challenges.

From the wars raging in Europe and the Middle East, to the growing influence of global rivals like China, to the potential proliferation of nuclear weapons in Iran and North Korea.
