AFGHANISTAN, February 25 - Russian President Vladimir Putin began a large-scale invasion of Ukraine on February 24 likely aimed at full regime change and the occupation of Ukraine. Russian forces met several setbacks on the first day of major offensive operations. However, Russian forces remain much larger and more capable than Ukraine’s conventional military. Russia will likely defeat Ukrainian regular military forces and secure their territorial objectives at some point in the coming days or weeks if Putin is determined to do so and willing to pay the cost in blood and treasure.
