Past is the key to the future. We need to look at it and learn from it. But is that so? We live in the past whether we want to admit it or not and although most wish to forget about their past experiences, it is much better to embrace and reflect on them. Past is not only educational for us, it is also a key to success in politics. We can see it through today's America's elections. Doland Trump is wishing to mark all Muslims in the US so that if there is an emergency, policemen knew who is more likely to be blamed. Doesn't it remind you of something? No? Well, beginning of WW2. Hitler decided to mark all Jews and transport them to a separate place far away from the rest. We need to look at past and reflect on it, as that way we can avoid many mistakes.
