Why is the Russian offensive not going at full speed?

The Ukrainian military says that Russia is seeing major setbacks, and its advance has slowed significantly.

Meanwhile, Ukrainian President Volodymyr Zelenskyy addressed the House of Commons by video link Tuesday evening and received a standing ovation after paraphrasing one of Winston Churchill’s famous wartime speeches in vowing his continued resistance to Russia’s invasion.

“We will not give up, and we will not lose.  We will fight to the end, at sea, in the air.  We will continue fighting for our land, whatever the cost, in the forests, in the fields, on the shores, in the streets,” Zelenskyy said.

The Ukrainian president added his country was fighting for its survival and called on UK lawmakers to continue applying pressure on the Kremlin with sanctions.

Zelenskyy’s address to a packed house in the Westminster chamber came shortly after the UK announced it would be phasing out imports of Russian oil in response to the invasion of Ukraine.

US President Joe Biden said that the US will also no longer import Russian oil.

“We will not be part of subsidizing Putin’s war,” Biden said.  Energy imports provide a vital source of income for the Kremlin.
