What was suprising to me, is that this hasn't been the longest continuous interval in which the US was in a state of emergency. Apparently:[1]

"During the Watergate scandal which erupted in the 1970s after President Richard Nixon authorized a variety of illegal acts, Congress investigated the extent of the President's powers and belatedly realized that the U.S. had been in a continuous state of emergency since 1950....The Act terminated the emergency of 1950 on September 14, 1978"

So,currently only halfway through the US's longest state of emergency, which lasted 28 years.
