As Russia’s offensive against Ukraine continues, a resident in the front-line city of Bakhmut is seen taking a break while carrying empty ammunition boxes on the street.

As the one-year anniversary of the war in Ukraine is fast approaching on Friday, Al Jazeera interviewed Pavel Felgenhauer, a Russian defense analyst, and former high-ranking research officer in the Soviet Academy of Sciences.

According to independent military analyst Pavel Felgenhauer, an expert in Russian foreign and defense policies, military doctrine, arms trade, and the military-industrial complex, the war is expected to intensify but could be concluded within this year. Given the intense nature of the combat, he asserted that the conflict would likely last up to 12 months.

Who will eventually win a decisive triumph?

Experts agree that it is impossible to predict what will happen.

Pavel Felgenhauer: It is impossible to forecast all future developments accurately. However, a sharp increase in hostilities is imminent. Talk of a Russian offensive is ubiquitous, and Western military authorities in Brussels have suggested that Ukraine should take the initiative and attack. General Mark Milley [Chairman of the US Joint Chiefs of Staff], who a year ago suggested Kyiv could be captured within a few days, now claims that Russia has been defeated strategically, operationally, and tactically. Therefore, Ukraine should take the opportunity to finish them off.

Ukraine is preparing for something; as Sun Tzu said, war is about trickery. If you are planning an attack and are in a strong position, you have to act like you are not, and the opposite for if you are not as strong. So, there are plenty of false reports out there. Both sides are aiming for the element of surprise.

In September, the Ukrainians executed a successful surprise attack in Kharkiv, accomplishing a great deal. Not only did they seize several significant strategic points and compel the Russians to retreat from Kherson to gain access to their reinforcements, but they also compelled them to initiate the mobilization process, which brought about several economic and political difficulties.
