  Are short range correlations in the ground state of the target nucleus
(initial state correlations ISC)observable inexperiments on quasielastic
$A(e,e'p)$ scattering at large missing momentum $p_{m}$? Will the missing
momentum spectrum observed at CEBAF be overwhelmed by final state interactions
of the struck proton? Taking the $^{4}He$ nucleus with a realistic model wave
function for a testing ground, we present a full calculation of the missing
momentum distribution in inclusive $^{4}He(e,e'p)$ scattering. We find a
complex interplay and strong quantum-mechanical interference of FSI and ISC
contributions to scattering at large $p_{m}$, with drastic change of the
interference pattern from the (anti)parallel to transverse kinematics. We show
that in all the kinematical conditions, for missing momenta $p_{m}\gsim
1$\,fm$^{-1}$, quasielastic scattering is dominated by FSI effects and the
sensitivity to details of the nuclear ground state is lost. The origin of the
FSI dominance is well understood and can be traced back to the anisotropic
behaviour of FSI which is long ranged in the longitudinal direction and short
ranged in the transverse direction in the opposite to the short ranged ground
state correlations.
