We prove that on any symplectic manifold whose symplectic form represents a
rational cohomology class there exists a sequence of compatible almost complex
structures whose Nijenhuis energy (the $L^2$-norm of the Nijenhuis tensor)
tends to zero. The sequence is obtained by stretching the neck around a
Donaldson hypersurface.
