Also, what business is it of the US (regardless of whom is in the White House) to declare the capital of another country? Should that not be up to the country and its citizens? It seems to me that by doing this Trump is going to open up a large can of angry snakes and undo whatever positive relationships the US had with Israel and the other countries in that region. Scary.

Thank you for the mostly mature and informative answers. Even in this fairly anonymous forum, I am quite embarrassed of my lack of knowledge. I asked my husband, who is a history geek and has earned a Master's of Divinity degree. He knows I don't like Trump and he changed the channel from the news conference. It didn't help that I was cranky from a clogged painful ear. It was not the time for a discussion. Again, thank you. I will likely do more research.
