The "second Cold War" and Cold War 2.0

A DUer recently pointed out that the "second Cold War" occurred when Reagan was president. According to Wikipedia, this is mostly correct:

"Second Cold War" (1979–85)
7.1 Soviet War in Afghanistan
7.2 Reagan and Thatcher
7.3 Polish Solidarity movement and martial law
7.4 Soviet and US military and economic issues
https://en.wikipedia.org/wiki/Cold_War

Wikipedia lists four periods of the cold war:
-Beginnings of the Cold War (1947–53)
-Crisis and escalation (1953–62)
-Confrontation through détente (1962–79)
-"Second Cold War" (1979–85)
-Final years (1985–91)
-Aftermath

The New Yorker Magazine's March 16, 2017 issue contained "Trump, Putin and the New Cold War" which has a section "Cold War 2.0."

With recent revelations of cyber war, it's hard to imagine we aren't already in a new Cold War. Experts on some Sunday shows say that a cyber war would involve actual physical damage occurring as a result of the hacking. However, if Trump sits on his tail and doesn't do anything, it would be called surrender.
