Military and intelligence officials say it looks like Iran launched the airstrikes but the U.S. has been slow to respond.

In the general's upcoming leadership book, Call Sign Chaos, the Obama administration catches the most flak. Mattis barely mentions President Trump but implies criticism of the sitting president.
