On this week's episode of the Defense & Aerospace Business Report, sponsored by Bell Helicopter, a Textron company, we discuss the enactment of President Donald Trump's tax reform, Congress' passage of a continuing resolution to avert a government shutdown, reported talks between Embraer and Boeing, and more. We also review the year in all-things defense, from the Pentagon to Wall Street. This week's guests include Richard Aboulafia of the Teal Group, Gordon Adams, PhD, American University professor emeritus and Stimson Center distinguished fellow, Byron Callan of Capital Alpha Partners, Ron Epstein, PhD, of Bank of America Merrill Lynch and former Pentagon Comptroller Bob Hale, who now advises Booz Allen Hamilton (his comments are his own).
