There has been long-standing debate about the physical state and possible phase transformations of confined liquids. In this report we show that a model confined liquid can behave both as a Newtonian liquid with very little change in its dynamics or as a pseudo-solid depending solely on the \it rate of approach of the confining surfaces. Thus, the confined liquid does \it not exhibit any confinement induced solidification in thermodynamic equilibrium. Instead, solidification is induced kinetically, when the two confining surfaces are approached with a minimum critical rate. This critical rate is surprisingly slow, of the order of 6 Å/s, explaining the frequent observation of confinement induced solidification.
