Nit pick: heard Trump has known “since March”. That could be 1-2 days or a full month or anywhere in between. And, of course, the question remains, _which_ IC?
I hadn't heard that.
But one of two options apply here. In my fevered imagination, anyway.
First of all, for the Israelis to go get the intel in January, which I think they have stated that they did. They would have to have known about it some time before that, right?
Anyway, beside the pernt. Would Israel share their intelligence with American intelligence? Do they trust them? do they have two teams of intelligence services working against each other like we do?
It could be very true that Israel didn't share the intelligence with us until March. But in my world, the could have identified that we now have a sympathetic ally in Trump and his white hats. Surely if they do, they know who to talk to by now.
Anyway, thank you for the nit pick. :)
