President Joe Biden is out to sustain the global alliance punishing Russia for its invasion of Ukraine as he embarks on a five-day trip to Europe as the 4-month-old war shows no sign of abating and its aftershocks to global food and energy supplies are deepening.

Biden first joins a meeting of the Group of Seven leading economic powers in the Bavarian Alps of Germany and later travels to Madrid for a summit with leaders of the 30 NATO countries. The visit comes as the global coalition to bolster Ukraine and punish Russia for its aggression has showed signs of fraying amid skyrocketing inflation in food and energy prices caused by the conflict.
