I'm glad Haaretz translated such an important article. Shlomi Eldar is an amazing journalist and each of his articles is a must read.
If Israel loses international support completely, there is a possibility.
Israel could lose all international support and still destroy all of Gaza with only internal resources. For Hamas to destroy Israel would require international military support, much more than the clandestine support to date.
They could, but how long would the country be able to defend itself against all its enemies, especially after such a heinous act of genocide?
What Netanyahu’s government is dangerous enough to the long term existence of the country. Going all in could be disastrous.
If Israel's enemies got to the point where they could make serious inroads and and news channels were full of Hamas and Hezbollah atrocities public opinion would flip in a second.
In realpolitik terms it is an acting what governments (e.g. Biden worried about 2024 elections) around the world are doing. The support continue behind the scenes. Israel is strategic.
