Abstract: Several no-go theorems showed the incompatibility between the locality assumption and quantum correlations obtained from maximally entangled spin states. We analyze these no-go theorems in the framework of Bohm's interpretation. The mechanism by which nonlocal correlations appear during the results of measurements performed on distant parts of entangled systems is explicitly put into evidence in terms of Bohmian trajectories. It is shown that a GHZ-like contradiction of the type $+1=\ensuremath{-}1$ occurs for well-chosen initial positions of the Bohmian trajectories and that it is this essential nonclassical feature that makes it possible to violate the locality condition.
