Hezbollah did fire missiles into Israel, but how "massive" it was, I don't know. It doesn't look so massive to me.
The Iron Dome failure is presently unverified, but some videos on this zerohedge report appear to show Iron dome failure.
All and all it doesn't look like much, and the Israeli's are saying: "Defense Minister Yoav Gallant
told a meeting of defense leader, "We are in the days of vigilance and readiness, the threats from Tehran and Beirut may materialize and it is important to explain to everyone that readiness, preparedness, and vigilance are not synonyms for
fear and panic."
And from the Pentagon:
"The Pentagon has said it is speeding up its naval assets heading to regional waters, including the USS Abraham Lincoln carrier strike group and the deployment of the USS Georgia guided missile submarine, in anticipation for a potential Iranian attack on Israel."
