My mother says TV news keep saying Iranian attack on Israel within 48 hours. I have my doubts about intelligence forecasts on this issue.
I would expect considerable effort is being made to disrupt Iranian communications to frustrate their efforts to coordinate a large attack. That alone might delay said attack.
Yes the media are all excited about the prospect of our being involved in open warfare. They are salivating at the idea of Biden campaigning as “a wartime president.”
