America's identity abroad has long been defined by the second World War and years of Cold War struggle. But the new America has changed; its role and identity are in flux - and with them, the global balance of power.

In Three Choices for a Superpower, president and founder of the Eurasia Group, Ian Bremmer, calls for a completely new definition of America as a superpower - one that adheres to distinct priorities and values. He outlines the three choices facing the new America:

Be independent: America does not have an endless supply of blood and finances to spend on other nations. Rather, America will fare much better if it devotes its energies and resources to rebuilding strength from within.

Moneyball: America cannot afford every foreign fight in support of American values, but they must defend their interests wherever they are threatened. They must make tough decisions intelligently, with an open admission of America's limitations.

Be indispensable: To think that America can operate autonomously from the rest of the world is not only ignorant but also extremely dangerous. The world relies on American leadership, and America has international interests - they must continue their role as an indispensable nation and remain actively involved abroad.

As the 2016 presidential election approaches, America needs to define its responsibilities, opportunities, and most importantly, its limits. A foreign policy divided against itself cannot stand; as the world's greatest superpower, America must choose which path it will follow into the future.
