Final answer:
The invasion in question is Russia's of Ukraine, driven by Russia's aim to counter Ukraine's shift towards Western alliances and to assert its own regional dominance.
Step-by-step explanation:
Russia's invasion of Ukraine was at least partially motivated by a goal of undermining that country's increasing political tilt toward the West. This geopolitical move has historical precedents, stretching back to tsarist expansions and strategic incursions into what now constitutes Ukrainian territory. From the annexation of Crimea in 2014 to the full-scale invasion that began on February 24, 2022, Russia has sought to assert its influence and contest the westward alignments of Ukraine. Under President Vladimir Putin, Russia is vigorously pushing against NATO's influence and trying to reclaim what it sees as its sphere of influence in Eastern Europe, which includes Ukraine, a nation with deep historical and cultural ties to Russia, yet one that has been making strides towards Western integration.
