1961–64 "chicken war" with Europe. With inexpensive imported chicken available, chicken prices fell quickly and sharply across Europe, radically affecting European chicken consumption. U.S. chicken overtook nearly half of the imported European chicken market. Europe instituted tariffs on American chicken, to the detriment of Arkansan chicken farmers. Senator Fulbright interrupted a NATO debate on nuclear armament to protest the tariffs, going so far as to threaten cutting US troops in NATO. The U.S. subsequently enacted a 25% tariff on imported light trucks, known as the chicken tax, which remains in effect as of 2010. One of Fulbright's local staffers in Arkansas was James McDougal.

In the same speech, Johnson asked Congress to a resolution to prove to North Vietnam and its ally China that United States was united "in support of freedom and in defense of peace in southeast Asia."
