You don’t need to speculate or theorize; they say exactly how they did it. I cut to the exact part of the video where it is succinctly explained.

You’ll also notice that, according to Ben/according to Israel/according to Hezbollah… they advertised that they were going to stop using phones & switch to pagers. In July. So people going on about “they could have done this all along” are wrong. It’s been since sometime in July. This July. Which makes this a very fast & even more effective military operation.
