Trump's Security Strategy Is Sound, If He Believes It

As a statement of policy, the U.S.'s new National Security Strategy is mostly unobjectionable. As an expression of President Donald Trump's worldview, however, it is oddly encouraging. The question is whether Trump will stand by the words that went out in his name.

The policy first: The greatest difference between this week's document and previous ones -- they are required by Congress -- is its emphasis on domestic security. Unfortunately, this is also the issue on which it is weakest. Promised new investment in border security, immigration control and domestic missile defense will not necessarily make Americans safer. And while it stresses the need for improved cybersecurity, there aren't many specifics to show that the administration understands the problem.
