All politicians meet with lobbyists. It’s hard to get a handle on the needs of the nation (or state, or so on), and lobbying is how people inform their representatives of that need. Now whether those lobbyists are scumbags or saints, that’s a different question.
The only people who had those pagers were Hezbollah members. Hezbollah has been lobbing missiles into Israel, killing civilians including children and forcing an evacuation. They picked a fight, why should there be an expectation that Israel just sits back and takes it? Don’t get me wrong about Gaza, they have gone way too far there. But Hezbollah seems at least somewhat justified.
