Maybe hard to swallow but might be true nonetheless:
Hamas had a historical victory. It will probably be its last.
Israel was put into a geopolitical corner with only one option: destroy Hamas, turn Gaza into Carthage and take control of it.
There was a lot of support for the Palestinian struggle among the Western public, that's mostly gone now.
The world had enough of the Arab-Palestinian/Israeli conflict after decades of slaughter, they don't care anymore if both sides just go to hell.
Nobody wants the conflict to expand into neighboring countries, neither Arabs, the West, China, Iran or Russia, so they'll let Israel turn Gaza into Carthage.
