In this talk I discuss the interpretation of these Monte Carlo results in terms of our current theoretical understanding of theta-dependence and topological structure in asymptotically free gauge theories.Talk presented at the 7th Conference on Quark Confinement and the Hadron Spectrum, Ponta Delgada, Azores, Sept. 2-7, 2006High Energy Physics - Theorytext
