The war of aggression against Ukraine by Russia, which began nearly three and a half years ago, continues to this day. In this war, both Russia and Ukraine have deployed large-scale ground forces to the front lines, engaging in full-scale ground warfare. However, was it really that President Vladimir Putin aimed to engage in a large-scale war to achieve victory? Many experts argue that President Putin's original objective was to establish a pro-Russian regime in Ukraine within a short space of time, perhaps about a week.
