Israel has vowed to keep fighting in Gaza until it crushes Hamas after one of the deadliest single battles of the war for its soldiers, even as it faces mounting international calls for a cease-fire and unease on the part of its closest ally, the United States. Hamas' resilience has called into question whether Israel can defeat it without wiping out Gaza. Support for Hamas has surged among Palestinians — in part because of the militant group’s stiff resistance to a far more powerful foe — while Israel’s most important ally, the U.S., has expressed growing discomfort over civilian deaths in what is already one of the 21st century’s most devastating military campaigns.
