  We reinvestigate the fate of the Vainhstein mechanism in the minimal model of
dRGT massive gravity. As the latter is characterised by the complete absence of
interactions in the decoupling limit, we study their structure at higher
energies. We show that in static spherically symmetric configurations, the
lowest energy scale of interactions is pushed up to the Planck mass. This fact
points towards an absence of Vainshtein mechanism in this framework, but does
not prove it. By resorting to the exact vacuum equations of motion, we show
that there is indeed an obstruction that precludes any recovery of General
Relativity under the conditions of stationarity and spherical symmetry.
However, we argue that the latter are too restrictive and might miss some
important physical phenomena. Indeed, we point out that in generic non
spherically symmetric or time-dependent situations, interactions arising at
energies arbitrarily close to the energy scale of the decoupling limit
reappear. This leads us to question whether the small degree of spherical
symmetry breaking in the solar system can be sufficient to give rise to a
successful Vainshtein mechanism.
