Seems like a harbrining of war, if the pager network was compromised, thus burns the compromised network and also harms a lot of people. Most major newspapers in Israel are saying that Netanyahu wants an invasion of Southern Lebanon: https://www.ynetnews.com/article/bje3pjv60 https://www.jpost.com/arab-israeli-conflict/article-820399 https://www.timesofisrael.com/top-general-said-pushing-for-g...
I wouldn't necessarily call this type of attack a network compromise. All it takes is knowing the target phone numbers and sending a specific message, which is a paging network working exactly as designed. Phone detonated bombs have been a thing for a long time too.
Calling it a hardware supply chain attack seems more accurate.
