They'll never keep real siege neighbors down.

Going to be credible for a second here (sorry)

They are launching fire and accelerant into the already existing fire to do two things. 1) suck out all the oxygen to stop the natural fire from spreading and b) to burn up quickly all the current combustible material.

In forest fires you often fight fire with fire, either by burning out areas in front of the fire in a controlled manner so when the fire arrives there's nothing to burn hot enough to spread or by making the fire die out.

The trebuchet is almost certainly because the fire is far too hot to get close enough to get the accelerant into the fire deep enough that it doesn't just spread it more.

The real explanation is the exact opposite.

This is the border with Lebanon, they're deliberately starting fires on the Lebanese side to burn down the thick shrubbery and forests that Hezbollah uses to get close to the border.
