Uganda purchasing SU27 advanced long range fighter bombers and Egypt recently placing increased emphasis and resources on training military units(including western training efforts) responsible for upstream Nile force projection is not a coincidence.
Nile resource sharing is a massive flash point.
I recall glancing at an engineering report that indicated clearing/dredging swamps in Sudan could significantly reduce mile water evaporation and increase downstream flow.
But at massive environmental and financial cost.
Perhaps it’s time to stock up on Egyptian cotton sheets now, since the future of Egyptian cotton may seriously be in doubt.
Tough choices to be made amplified by the need for them to be across sovereign borders.
