In the best of times, people might think you are crazy for getting a second passport, or foreign citizenship.

But what about on the brink of World War 3? Perhaps now is the time to give yourself some options.

If you are American or British, the last thing you want is to be trapped. Imagine if a U.S. passport–arguably the most cherished passport in the world–suddenly couldn’t get you across borders. This could happen if a foreign coalition raises international pressure to stop the U.S. from aggressive action in the Middle East.

But the U.S. government itself could revoke your permission to travel for any number of reasons. They can cancel an individual’s passport without explanation. And as we inch towards more intense nationalism, it is unfortunately not so far-fetched that the U.S. would limit their own citizens travel opportunities wholesale.

At that point, it will pay off to have a passport from Panama or Italy. It means you can still travel to many places without the U.S. having a say. It means you can flee in the face of American military escalation, martial law, natural disaster, or financial collapse.
