What's the difference between a floating incendiary device and a Nazi-era buzz bomb?
NOTHING. Both are meant to maim and kill.
The IDF should be attacking, with lethal force, anyone launching or helping to launch a fire kite. Very simple. Any kite should be considered as if it was a mortar or rocket about to be launched. Vaporize the terrorists. Very simple.
Netanyahu's response via the IDF had better be biblical.
