It Is Decision Time for NATO

The 62nd Munich Security Conference, otherwise known as "Davos with guns," has arrived at a pivotal moment. The United States has never demanded more of Europe, and Europe has never expected less of the United States.

The conference, which began on Friday, is a fork in the road for the trans-Atlantic relationship. Of the two paths before us, one is a lasting recalibration of the NATO alliance with a strong Europe at its core, capable of defending itself while sustaining a healthy, if diminished, partnership with the United States. The other is continued trans-Atlantic infighting over shared values, national interests and what counts as a fair division of responsibilities on all sides.
