At the same time Russia risks getting stuck in a protracted battle against Daesh in Syria and is also in need of allies, she points out.
Therefore, circumstances allow Russia and Europe to establish cooperation by dealing with issues that "poison" their relations, Calmy-Rey concludes.
As the potential integration of Russia into the European security system would be a difficult and delicate issue, Calmy-Rey offers a "more pragmatic" and "less ambitious" but at the same time "more realistic and effective" solution by using the existing relations between the EU and Switzerland as a template.
She also suggested making Russia a privileged economic partner of the EU which wouldn’t contradict both the norms of the Eurasian Economic Union and the EU association treaties.
"History teaches us that the safety and prosperity of Europe can only be secured with the help of Russia," Calmy-Rey said, adding that the growing rapport between the EU and Russia is therefore inevitable.
