Russian deployment of troops on the Ukrainian border is a clear threat of war, which the US-led Western block perceives truly. This research aims to analyse Russia's motives for opposing Ukraine. Europe's geopolitical and geo-economic situation needs serious attention to be studied systematically. A qualitative fact-based approach is used, and a descriptive analysis has been done for this research. The current security dynamics amidst the Russia-Ukraine conflict have jeopardised the security structure of the entire European region. All such development is no doubt a threat to the security of Europe. One of the immediate reasons Russia deployed its troops on Ukraine's border was to stop Ukraine from joining NATO, for which Russia had threatened both Ukraine and the US-led Western block. As the Ukraine crisis unfolds, geopolitical shifts have pushed Russia and China closer together. Consequently, this closeness between China and Russia is seen as alarming in the West. Further, the crises have highlighted differences within the Western alliance, like no consensus, as they do not agree on how to respond to this worst situation. It has further intensified the polarisation of the East and the West and has raised tensions.
