History Lessons

I am always interested in learning about historical events, and have read fact based historical fiction for years. Recently, I have been watching the Vikings series, on the History channel, and find it is historically correct.
It is widely known that facts from both World Wars and certain events in history involving the Americans, with or without the addition of Britain, Australia, Canada, France, and other European partner countries, and before the organization  of NATO, (which was set up in 1949),  have been altered to enhance American involvement, so that most Americans believe that they won all of the wars they were involved with, singlehanded .
Last year, Ray and I watched Oliver Stone's fascinating series, the Untold History of the United States, chronicling these major events, making an effort to straighten out the belief that America won the war....it is little wonder that his series has not been taken up for a second season.
As I said, history is very interesting, yesterday, we saw the movie the Woman in Gold, a true story about a family trying to reclaim paintings that had been stolen from them just before World War 2, by the Nazis and kept from them after the war by the Austrian Government. Thankfully, the family persisted through the many obstacles thrown at them, by the Austrian government, and others, and won the right to take their property back.
Even though this movie was a win for this family, it will never change the fact that their lives will never be the same, or that their lives were irrevocably changed by World War 2 and the atrocities suffered by the Jews and others in that war, and no amount of restoration/ reclamation will ever make up for what they lost.
History is a great teacher, we should try to learn the lessons of the past in order to avoid the same mistakes in the future.
