Russia was building trust for years beforehand. Putin spoke twice in the Bundestag for example, the goal was a free trade zone from Lisabon to Wladiwostok. Russia also asked to join NATO. It got declined both times. Even when the coup happened in Ukraine, Russia attempted multiple diplomatic initiatives to deescalate the situation.

Do you know who always escalated? Who was always pushing for conflict? Hint: It wasn't Russia.
