Does Ukraine and Zelensky have any other plan than to propagandize the West and hope to bring the U.S. and Europe into the war? From Moon of Alabama at moonofalabama.org:
The Ukraine Is Still Losing So What Is Its Plan?
Russian and Donbas forces have cleared the city of Mariupol except for the giant metallurgic complex of Azovstal which is held by some estimated 4,000 men, including many from the fascist Azov battalion.
On Sunday Russia opened corridors across the front line and asked for those forces to surrender. However the Zelensky government ordered them to stay and to continue to bind Russian forces which otherwise could be used elsewhere:
Russia had given the Ukrainian fighters in Mariupol until Sunday morning to lay down their weapons or be “eliminated.” On Sunday, the forces at the plant ignored the deadline, and Ukrainian officials vowed that they would not surrender. In response, the Russian assault intensified, with missiles and bombs hitting the city and new attacks occurring near the plant, according to the Ukrainian military.
Ukrainian officials said on Sunday that the struggle was not over for Mariupol, which for two months has tied up Russian troops and resources that are badly needed elsewhere.
The Azovstal complex is a 2 by 2 miles industrial area. It can be surrounded and controlled by a relatively small force. Those within the area no longer have heavy artillery ammunition and presumably little other supplies. The Russian forces can see and bomb anything that moves on the open ground and can otherwise sit back and wait their enemies out.
