Donald Trump’s speech on national security at the Union League of Philadelphia Wednesday may have been his best imitation of a traditional, conservative Republican to date, particularly on his proposals to rebuild the U.S. military. When The Donald cites the 2014 National Defense Panel report, he’s gone Establishment with a capital “E.” Further, the speech was a succinct, devastating, and, setting aside the excesses of Trump’s anti-Hillary Clinton animus, quite substantive attack on Obama-era strategy.
