Well, by unrealistic they meant it's not economically realistic - you can fire silver iodide crystals into cloud formations and cause weather systems to move, but it only works on certain systems, isn't 100% effective, costs tons of money, and you're dropping shit all over the countryside at an enormous cost of fuel, resources, and environment. Not to mention glaciating clouds causes dangerous buildup in jet engines which also puts the pilots lives at risk.
that's helpful at understanding this, however you still can't control the direction of weather, and that is what is completely unpredicable
at least for any realistic 'target'
you would be extremely lucky to even hit the right city
really this is comical at best
amazing it can even be done, but not usable to the extent of a weapon
that is unless you are saddam hussein and gassing entire areas is 'accurate' , .... i e a madman
