Now that there are drought conditions all over the western USA, I have a question to those who know something about this.

When I was a high school student, our Physics teacher announced one day with a big smile on his face, that:

1. "The USA has the technology and the ability to implant iodine into clouds and create rain". That was half a century ago, so why are we having a drought this year? don't we have iodine?

2. "The USA can desalinate sea water for human consumption", so why is the USA doing it only in the middle east and not here at home?
