Will there ever be another peacetime president?

[President Punxsutawney Phil]

Carter was president during the war on drugs.

I suppose that along that logic you can say that Calvin Coolidge was president during the war on Christmas.  Frankly I think that including the War on Drugs is nitpicking - considering how, if you do include it, the last peacetime president becomes Kennedy - but if you exclude him, Hoover.

Hmm...I felt that including Kennedy was somewhat dubious but i nonetheless included him because at the time it really felt like peacetime.  Nonetheless I see your point.
