He hears what he wants to hear, and disregards what he doesn’t. Intelligence information must comport to his worldview for it to stick. If it doesn’t, it’s “not very good.” As a result, the president of the United States is often ignorant on the most serious national security threats we face and is, therefore, ill-prepared to defend against them. In fact, I’d submit that he’s less informed than he should be on almost every major global threat, from nuclear weapons proliferation to cyber security.
