I must admit that when I first heard of this I laughed at the
technical simplicity and cleverness of it all.
Of cause some were killed and many injured, but they were all members
of a terrorist organisation.
Somehow "they" got hold of the pagers between the manufacturer and
Hezbollah and inserted the explosive and made a connection to the
addressing logic in the pager. Just getting ready to do that would
take quite a while.
Then "they" had to send a signal into the pager network addressed
to all pagers.
It would be interesting to know if people in Lebanon with pagers
for other purposes got the same message on their screen.
I wonder what it said.

One child was killed when she fiddled with her terrorist father's pager, but otherwise the right people copped it.

A brilliant operation. There is no doubting Israeli ingenuity and determination to protects itself.

It upset the ABC greatly, prompting much discussion of the action as a war crime.

Yes, very unlucky that the child had the pager. Still in a war that
is exactly what happens, just bad luck. Don't start a war !
I wonder if her father regrets joining Hezbollah ?
FYI the pager transmitter sends transmissions for all pagers whether
they are the one customer or many customers, and the pager
that hears its address then keeps the message, other pagers just let
the message go to the bit bucket. That keeps the msg private.
That is why only Hezbollah pagers accepted the message and detonated.
Hezbollah can only now go to a manufacturer and take them directly
off the production line provided the manufacturer is not in the act
with "them".
I wonder if Hezbollah members will now accept ANY pagers ?

Some people have not, and will not, condemn the Hamas atrocities against Israeli civilian men, women, children and babies that stared the war, but they start barking when a single child is unintentionally killed because her father is a terrorist.

Netanyahu got what he wanted - there will be no cease-fire, these hostages which give him such a headache will soon all be dead, then he can keep the war going forever, and come 2026 he could cite this never-ending war as an excuse to postpone the Israeli elections and remain in power indefinitely like Putin his friend, meanwhile as despairing liberal Israelis leave the country which helps his electoral demography.

But he must be careful not to kill too many Arabs, only a few thousands here a few thousands there, not enough to win the war, just enough to brag about and show cause for his existence, but not kill too many because if all Arabs are finished, so would the war...

Sinwar, Nasrallah and Khamenei all share that interest so they can all remain in power, no matter how many of their own are killed. There is every reason to believe that the four are coordinated, making sure that none of them ever wins nor loses the war.
