When it comes to analyzing and understanding the global crazy events at all levels, ignoring unintentionally or intentionally the past events is a disaster.
If we want to understand the current pandemic of Covid-19, we must understand and analyze the previous pandemics to decipher this one.
If we want to understand the current financial crisis resulting from Covid-19, we must drill down on the previous financial crises. The causes and the effects.
If we want to understand and predict WW3, we must carefully study WW1 and WW2. The causes and the effects.
Ignoring history is a disaster and not understanding how it was molded is a catastrophe.
