Abstract

I discuss how the solution of the U(1)AU(1)_A problem of QCD through the existence of the θθ-vacuum gave rise to the strong CP problem. After examining various suggested solutions to this problem, I conclude that the only viable solution still is the one that involves the existence of a spontaneously broken chiral symmetry: U(1)PQU(1)_{PQ}
