A spin-off of the Palestinian branch of the Muslim Brotherhood in the late 1980s, the Islamist militant group Hamas took over the Gaza Strip after defeating its rival political party, Fatah, in elections in 2006.
Hamas has a host of leadership bodies that perform various political, military, and social functions. General policy is set by an overarching consultative body, often called the politburo, which operates in exile. Local committees manage grassroots issues in Gaza and the West Bank.
Hamas’s assault on southern Israel this year, which the group’s leaders have called “Operation Al-Aqsa Storm,” was extraordinary in its strategy, scale, and secrecy, analysts say. It began early in the morning on October 7, the Jewish Sabbath and an important Jewish holiday, with Hamas launching several thousand rockets into southern and central Israel, hitting cities as north as Tel Aviv. Hamas militants also breached the heavily fortified Gaza border and infiltrated many southern Israeli towns and villages, killing hundreds of Israeli troops and civilians, and wounding and kidnapping scores more.
Hamas’s military leader, Mohammed Deif, said the group undertook assault because of Israel’s long-running blockade of Gaza, its occupation of Palestinian lands, and its alleged crimes against Muslims, including the desecration of the Al-Aqsa Mosque in Jerusalem.
It is the deadliest attack on Israeli soil in decades and has inflicted a deep psychological trauma on the Israeli people, with some analysts drawing comparisons to the surprise Pearl Harbor and September 11, 2001, attacks on the United States. Israeli and U.S. intelligence agencies reportedly had no indications that Hamas was planning an assault of this nature. “It is completely unprecedented that a terrorist organization would have the capacity or the wherewithal to mount coordinated, simultaneous assaults from the air, sea, and land.
Israel has declared war on Hamas and countered with intensifying airstrikes on targets in Gaza and ground operations to push the group’s militants out of the country. The government has ordered the evacuation of all civilians from Israeli communities bordering Gaza. Prime Minister Benjamin Netanyahu has warned of a “long and difficult war” against Hamas, and Israel’s military response is expected to be extraordinary, if not unprecedented.
Some observers are questioning if Israel will attempt a full-scale invasion and reoccupation of the Palestinian territory, a campaign that could incur heavy casualties on both sides. “Israel had mounted numerous military operations against Hamas since its takeover in 2007, two years after Israel pulled out of Gaza. But these were mostly from the air. And even when Israeli troops were deployed, they never stayed for long.
An Israeli invasion of Gaza could also provoke a significant attack against Israel by Hezbollah, the Iran-backed militant group in Lebanon, risking a wider conflagration in the region, analysts say. “Iran is, of course, a patron of Hezbollah [as well as other Palestinian militant groups] and there is an ever-present danger of a two-front conflict, which would devastate parts of Israel and much of Lebanon, where Hezbollah is based. There is a risk of escalation.
