thing is Its not a new idea. been around a long while ( similar ideas were apparently shown in the Snowden Wikileaks ) but not used in such a large scale before.
and it really was an ingenious bit of planning, clearly a multi year operation to disable an enemies ability to function properly. something can be horrific and ingenious at the same time.
Yes it will be copied but then all weapons are. a few weeks ago Ukraine unveiled a thermite spraying drone. in 2/3 months Russia will have the same. its the nature of warfare.
the issue for me is that Israel doing this ( cant really pretend its anyone else ) seems to have moved from a bit of a tit for tat fire fight on the border or the odd targeted bomb / missile to a full on attack. I cant see this being anything but the start of a full Israel Hezbollah war.
