French President Francois Hollande said Friday Russia should not be considered a threat but rather a partner, as Nato leaders met to endorse a revamp to counter a more aggressive Moscow. "Nato has no role at all to be saying what Europe's relations with Russia should be. For France, Russia is not an adversary, not a threat," Hollande said as he arrived for a landmark alliance summit in Warsaw. "Russia is a partner which, it is true, may sometimes, and we have seen that in Ukraine, use force which we have condemned when it annexed Crimea," he added.
