This study on Active Measures Working Group is a must read to understand the context of, and develop a better perspective on what is happening today. The similarities in the global race for power and influence and the role of information warfare are berraly deja vu all over again! The relevance is not just with the Russian influence and interference with the elections but a general clarity on real world challenges that can not be denied or wished away. Everyone does it to a different extent. Intent, degrees and thresholds matter too.
Reading is good for you, and sadly a good portion of people, political and bureaucratic leadership do not engage in substantive and reflective reading.
Populist pleasing postures and cynicism at the expense of systematic and methodical analysis of facts and intelligence, mixed with the extent of political denial is dangerous and ultimately damaging to institutions and culture itself.
Some things do not change much and those who do not learn history are doomed to repeat it.
