Most likely most of them were though. I mean I don't think many people outside Hezbollah were using pagers, not to mention that most likely they tampered one or two batches of them only.
I am just wondering what the official government of Lebanon is thinking about this incident because in my opinion that's a huge blow into the sovereignty of a foreign country. Imagine something similar happens in Israel or the US, do you think those countries would sit on the diplomatic table and negotiate?
