  We study the Nucleon-Nucleon interaction in the Born-Oppenheimer
approximation at second order in perturbation theory including the \Delta\
resonance as an intermediate state. The potential resembles strongly chiral
potentials computed either via soliton models or chiral perturbation theory and
has a van der Waals like singularity at short distances which is handled by
means of renormalization techniques. Results for the deuteron are discussed.
