None of Russia's strategic objectives have been achieved over the 100 days of full-scale war it has waged against Ukraine, the UK Ministry of Defense said in its daily intelligence assessment update on Twitter on June 3.
"Today marks the 100th day since Russia's invasion of Ukraine,” the ministry's assessment reads.
“Russian forces failed to achieve their initial objectives to seize Kyiv and Ukrainian centers of government. Staunch Ukrainian resistance and the failure to secure Hostomel airfield in the first 24 hours led to Russian offensive operations being repulsed."
"Following the failure of the initial plan, through false planning assumptions and poor tactical execution, Russia adapted its operational design to focus on the Donbas."
According to the report, Russia is now achieving tactical success in the Donbas.
Russian forces have generated and maintained momentum and currently appear to hold the initiative over Ukrainian opposition.
"Russia controls over 90% of Luhansk Oblast and is likely to (gain) complete control in the next two weeks," the intelligence said.
"Russia has achieved these recent tactical successes at significant resource cost, and by concentrating force and fires on a single part of the overall campaign."
It is noted Russia has not been able to generate movement on other fronts or axes, all of which have transitioned to the defensive.
"Measured against Russia's original plan, none of the strategic objectives have been achieved," reads the report.
"In order for Russia to achieve any form of success will require continued huge investment of manpower and equipment, and is likely to take considerable further time."
