a. North Vietnamese troops were still in South Vietnam
Ford directed most of his energies to tackling the troubled economy (see the section I Recession and Urban Crisis). He also had to deal with the war in Indochina, which had not ended in 1972 despite Nixon and Kissinger's pre-election assurances. The South Vietnamese had scuttled cease-fire negotiations in December 1972 by insisting on the withdrawal of North Vietnamese troops, and the United States stepped up its aerial assault. A peace treaty was finally signed in Paris in January 1973, ending the long and ultimately fruitless U.S. intervention in the region. However, with North Vietnamese forces remaining in the South, the war was far from over.
