I guess liberals are now saying that weather modification is not possible they are currently claiming that it is impossible but it has actually happened during the Vietnam War. Beyond that we know that technology has gotten better since WW2.
We also have those some people claiming that the United States would never try diverting disasters away from huge population centers to more rural areas to preserve lives. This is also untrue. During the cold War the United States put nuclear war heads in rural areas because they would be the first targets in a nuclear war and because it would save lives.
So this whole assertion that there is a conspiracy and the government would never modify weather is absurd, it's almost as bad as the cynicism of the left saying that the government is so evil they would never ever divert disasters away from large population centers
