【英文】兰德报告：大争时代日、欧联盟越来越紧密（132页）

In its 2018 National Defense Strategy, the United States acknowledged the reemergence of  long-term strategic competition with several rivals, including China and Russia. Some of the  United States’ most powerful and trustworthy allies are Japan and its European partners.  What is not always fully understood, or at least documented in great detail, are the types of  cooperative activities these allies are pursuing in the security domain amid this return of strategic competition. This report presents the results of a RAND Corporation study examining  how allies of the United States are increasingly cooperating with each other in the security  domain. 

With a focus on the increasing bilateral security links between Japan and the North  Atlantic Treaty Organization and three European states—the United Kingdom, France, and  Germany—I sought to build on extensive work done by European and Japanese scholars to  both understand and assess developments in these relationships and why they matter for the  United States. I found that, although the discrete lines of effort by these actors are at varying  levels of development, their security cooperation matters and it should be both recognized and  fostered.
