Results obtained in two recent papers, \cite{Kaszlikowski} and \cite{Durt},seem to indicate that the nonlocal character of the correlations between theoutcomes of measurements performed on entangled systems separated in space isnot robust in the presence of noise. This is surprising, since entanglementitself is robust. Here we revisit this problem and argue that the class ofgedanken-experiments considered in \cite{Kaszlikowski} and \cite{Durt} is toorestrictive. By considering a more general class, involving sequences ofmeasurements, we prove that the nonlocal correlations are in fact robust.Comment: Reference added, 3 pages, accepted for publication in J.
