Israel is vowing to wipe out Hamas in a relentless onslaught on the Gaza Strip but has no obvious endgame in sight, with no clear plan for how to govern the ravaged Palestinian enclave even if it triumphs on the battlefield.

Codenamed "Operation Swords of Iron," the military campaign will be unmatched in its ferocity and unlike anything Israel has carried out in Gaza in the past, according to eight regional and Western officials with knowledge of the conflict who declined to be named due to the sensitivity of the matter.

Israel has called up a record 360,000 reservists and has been bombarding the tiny enclave nonstop following Hamas's assault on southern Israel on Oct. 7, which killed about 1,400 people, mostly civilians.
