Russian President Vladimir Putin's announcement on Wednesday of partial mobilization is drawing cynicism from Ukraine and Western countries.

Ukrainian presidential adviser Oleksiy Arestovych indicated on social media that the mobilization is not expected to greatly change the current situation of the conflict in Ukraine.

He said that those to be mobilized lack and have extremely low combat effectiveness. He also claimed that many of those to be mobilized are secretly opposing the war.

Arestovych indicated the view that the mobilization will only result in accelerating the collapse and revolution in Putin's Russia.

Another Ukrainian presidential adviser, Mykhailo Podolyak, mocked Putin's latest move in a tweet, saying what Russia claimed to be the "three-day war ... ended up getting mobilization." He also said, "Everything is still according to the plan, right?"

Meanwhile, US Ambassador to Ukraine Bridget Brink slammed Putin's announcement of partial mobilization and his support for plans for referendums in Russian-controlled regions on joining Russia.

She said in a tweet, "Sham referenda and mobilization are signs of weakness, of Russian failure." She went on to say, "The United States will never recognize Russia's claim to purportedly annexed Ukrainian territory, and we will continue to stand with Ukraine as long as it takes."

German Vice Chancellor Robert Habeck criticized the mobilization.

He told reporters that the move is a further escalation of the conflict in Ukraine. He added that it was "another bad and wrong step from Russia."
