There are drought resistant crop varieties (both GMO and non GMO kind). Problem is that the drought resistant ones usually have lower yield and farmers in general prefer prefer higher yield kind. The GMO ones usually manage to keep the yield high while achieving good drought resistance. But yes when the drought is severe enough it will kill any crop no matter what species or variety. Though usually drought does not result in total crop loss but lower yield. https://www.ers.usda.gov/amber-waves/2019/march/drought-tolerant-corn-in-the-united-states-research-commercialization-and-related-crop-production-practices/ https://www.ers.usda.gov/amber-waves/2019/march/drought-tole... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6651533/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6651533/
