What if the next world war isn't fought with missiles, but with rivers?

In Blue Siege, bestselling author William Liu uncovers the terrifying reality of water warfare-the ruthless manipulation of rivers, dams, and aquifers as the ultimate weapon of the 21st century. From China's stranglehold on the Mekong to Ethiopia's bid for Nile dominance, nations are already wielding hydraulic siege engines that can collapse economies, trigger refugee crises, and topple governments without a single shot fired.

This book takes you inside the new era of conflict, where every drought can be engineered, every dam doubles as a fortress, and survival depends not on oil or territory, but on H2O itself. Blue Siege is both a wake-up call and a survival map for a future where water isn't life-it's war.
