Well, there is drought resistant crops. Yes, it is true the crops can't grow without any water at all, but often times drought means less water, and that causes the crops to become more susceptible to disease. So that is one way of making a crop drought resistant, is to make it disease resistant.

Drought resistant not a silver bullet. It can help, but only up to a point (and that point seems lower than the sales guys and sponsored studies under optimal conditions might indicate).

Edited because part of this wasn’t factually correct.

> These are plants that have had genes from another organism inserted into their DNA to give them a new trait, such as disease or drought resistance

The article states they are wanting to use drought resistant strains. I am assuming the drought resistant could be translated as “plants that don’t need a lot of rain”.

there are gmo crops that rely on less water to grow - they'll use those. agree with your second point, possibly already there.

there are already crops that grow under less-rain conditions, but sales teams are checking your subscription status right now

The article mentions at least 5 things that are reducing food production. GMO addresses one of them.

That's indeed one great question
