This is why space based lasers don't work. It's a matter of energy input and the fact the laser which you perceive as a singular line of photons are actually more of a cone and the further the cone travels the larger it's bottom gets. The energy has a Gaussian distribution that gets less intense the further from the source you get due to the fact that the initial energy level at the source is now spread out over a significantly larger area.

Another thing, Pissrael has a large DEW but it's the size of a building. If you do choose to use a space laser and just brute force it you'd need at least a building sized energy source and by the time the laser hits the ground from space it's the size of a few city blocks.
If I had unlimited money and a need to kill people from space I'd use a particle accelerator. Tiny munitions, large kinetic energy. Or a railgun.
