Did WWIII Already Start?

Yesterday, I was in the finca trying to use my GPS to take some altitude readings. A few meters of variation is normal but I was seeing big variations--up to 24 meters. Well, the current GPS satellites are up there for the U.S. military. (EU ones are on the agenda soon.) When the U.S. military wants to, it varies the information a bit for us mortals.

The way it works is that the unencrypted data is fudged a bit but, with a magic key you can still get the more accurate info. That is so U.S. cruise missiles hit their target but "the other guy's" don't. The last time I saw this was when the U.S. was about to invade Iraq.

Not being sure if it was just a bad day because of trees, weather or whatever, I mentioned it to a friend in the U.S. He confirmed that the same thing was happening to him. So, it seems real. Does this have anything to do with Nicaragua? Yes, another reason I am glad I live here.
