1.the claud that turns to rain most of it comes from sea so it is possible to impose rain sunction by using claud seedin program. so who owns the river water? 2.Did you know that the dam slows the speed of runing water then the watter sinking deeper into the ground increses and contributes into land slides on the higher ground this means the whole addis ababa could be flouting on mad then slide. IT is hard to tell the directin of water underground. CLud seeding technology can only get cheaper and cheaper in the future. Stop blufing and try to understand what natural and artificial disasters can do to the dam and cause damage to others. Insurance 500 bollion us dollar you have to pay before you bluf. I have never seen the countries you insult i sulting ethiopia. I wish you to walk up.
