  We study the stability of the Quantum Critical Point (QCP) for itinerant
ferromagnets commonly described by the Hertz-Millis-Moriya (HMM) theory. We
argue that in $D \leq 3$, long-range spatial correlations associated with the
Landau damping of the order parameter field generate a universal {\it
negative}, non-analytic $|q|^{(D+1)/2}$ contribution to the static magnetic
susceptibility $\chi_s (q, 0)$, which makes HMM theory unstable. We argue that
the actual transition is either towards incommensurate ordering, or first
order. We also show that singular corrections are specific to the spin problem,
while charge susceptibility remains analytic at criticality.
