This is the best summary I could come up with:

None of the American assessments offered any tactical details or indications of the overwhelming scope, scale and sheer brutality of the operation that Hamas carried out on October 7, sources say.

But the assessments were among a wave of high-level warnings given to the Biden administration by both its own intelligence community and Middle Eastern allies over the past year, raising questions about whether the US and Israel were appropriately attuned to the risk.

A Middle Eastern ambassador in Washington, DC, also told CNN that their government had repeatedly warned the White House and US intelligence officials of a buildup of Hamas weapons and anger among Palestinians that was set to explode.

But US officials also believe that Israel had become complacent about the threat Hamas posed and failed to recognize key indicators that the group was planning for a large-scale operation.

Israel believed that its policy of offering work permits to Gazans and allowed Qatari money into the country had given Hamas something to lose — and lulled the group into quiescence.

“Hamas is very, very restrained and understands the implications of further defiance,” Tzachi Hanegbi, Israel’s national security adviser, told an Israeli radio channel six days before the assault.

The original article contains 1,278 words, the summary contains 201 words. Saved 84%. I’m a bot and I’m open source!

A state doesn’t care directly about a half dozen deaths, be them of citizens paying taxes to said state or to another state.A state cares first and foremost about continuing its existence, and secondarily about expanding its own power.

With that in mind:

• It’s arguable if USA had anything to gain sharing the assessment with Israel. Probably more to lose, as the attacks make Israel rely further on USA (USA expands its power over Israel).
• It’s also arguable if Israel had anything to gain by avoiding the attacks instead of retaliating them. The later made the state of Israel more sympathetic to the eyes of people and states elsewhere (soft power).

Welcome to the third planet.
