Last time I checked, foreign policy was a major portion of the Presidency
Nixon wasn't wrong on affirmative action. The programs just should have had a sunset date so that we would have had some sort of "equality target". IMHO, he should have based the programs on economic disadvantage rather than race, though.
Nixon is generally credited for making government much more efficient, eliminating unnecessary bureaucracy and procedures.
Nixon was a stalwart of law and order in a time of extreme social upheaval. He did his best to calm the nation and shepherd it through some of the toughest times in its short history.
Name some good things he accomplished that aren't related to foreign policy.
