Parker's coronal braiding and nanoflaring scenario predicts the developmentof tangential discontinuities and highly misaligned magnetic field lines, as aconsequence of random buffeting of their footpoints due to the action ofsub-photospheric convection. The increased stressing of magnetic field lines isthought to become unstable above some critical misalignment angle and to resultinto local magnetic reconnection events, which is generally referred to asParker's `nanoflaring scenario'. In this study we show that the {\sl minimum(magnetic) energy principle} leads to a bifurcation of force-free fieldsolutions for helical twist angles at $|\varphi(t)| = \pi$, which prevents thebuild-up of arbitrary large free energies and misalignment angles. The minimumenergy principle predicts that neighbored magnetic field lines are almostparallel (with misalignment angles of $\Delta \mu \approx1.6^\circ-1.8^\circ$), and do not reach a critical misalignment angle prone tonanoflaring. Consequently, no nanoflares are expected in the divergence-freeand force-free parts of the solar corona, while they are more likely to occurin the chromosphere and transition region.
