Independence Day arrives at a time when the United States is roiled by hearings over the Jan. 6 insurrection, awash in turmoil over abortion and guns and struggling to maintain the common bonds that keep it together. Yet many also see cause for celebration: The pandemic continues to be on the wane and, despite its faults, America’s democracy survives. July 4 marks the nation’s 246th birthday and anniversary of independence from English rule. It’s a day when people of all stripes flock to parades, devour hot dogs at backyard barbecues and gather under a canopy of stars and exploding fireworks.
