I'm thinking as democracies we should not rely on secret evidence. I'll buy it when it's public, until then the burden of proof remains on them. It's okay not to kmow.
"Blinken: U.S. received more info on Gaza tower bombing
American top diplomat says he cannot comment on further information received through intelligence channels on the destruction of the building that housed Associated Press, Al Jazeera offices"
I wouldn't say IDF couldn't provide. Classified evidence takes time to compile when being passed to foreign countries. If this was truly a Hamas operations office, it changes the whole picture.
