Well, it’s not like Israel is an ally.
It’s not like the politicized CIA is a reliable source of intelligence nowadays, either. Mossad probably knows more than them.
Israel is most definitely an ally. But it will not allow itself to be destroyed for political reasons, as the Biden-Harris Administration wishes it were.
The odds of the Pentagon telling the truth about anything approaches zero—so presumably they are providing that intelligence support.
Another possibility/likelihood is that the Pentagon spokesperson has no “need to know” such things so they are being fed disinformation and they are just repeating the lies they have been fed.
“We only monkey things up.” US policy.
