How does it help you understand the article Lebanon’s wave of pager explosions is a message to Hezbollah Is it a prelude to a wider attack or the totality of the message to Hezbollah? This is the key question for the next 48 hours in the Middle East, as the Lebanese militant group comes to terms with the wholesale disruption and violation of their most sacred communications. Tuesday’s wave of explosions in Lebanon will likely scar the Party, as they are often known, who pride themselves on secrecy, and the technological omerta their members adhere to. Yet it is their very bid to keep their secrets – using low-tech pagers and not more trackable smartphones – that appears to have led to several deaths and thousands of injuries. It will have caused a seismic shock with Hezbollah members to now be asking not only if it is safe to contact their colleagues, but if those colleagues are unharmed?       Israel has characteristically not claimed responsibility, but if it was behind the attack as Lebanon and Hezbollah say, then the question is whether this vast and unprecedented assault was intended to presage a wider fight. It would make strategic sense to dispense a moment of intense chaos like this just before a bigger onslaught on the group militarily. The timing is telling. Just on Monday, the Israeli defense minister Yoav Gallant said during a meeting with the US envoy Amos Hochstein that the time for diplomacy with Hezbollah had passed and military might could take center stage. Literally hours later, their enemy’s entire communications infrastructure was hit with an attack that, according to a Lebanese security source, used pagers purchased by Hezbollah in “recent months,” necessitating a long lead time in the operation’s planning.
