What event was seen that the second cold war had started

Answer 1

There is no definitive event that marked the beginning of the second cold war. However, some historians and analysts argue that tensions between the United States and Russia have been escalating since the early 2010s, with events such as the annexation of Crimea by Russia in 2014 and the ongoing conflicts in Syria and Ukraine being seen as key flashpoints. Additionally, the breakdown of arms control agreements and the increasing militarization of both countries have also raised concerns about a new cold war.
