It's not known when the war will end, but supplying Ukraine with modern weapons would increase its chances of expelling the Russians from eastern Ukraine.

The British Ministry of Defense said in a Sunday intelligence update that both Russian and Ukrainian troops are likely to be in a state of low spirits because of the conflict in the east of the country.

There have been cases of entire Russian units refusing orders and armed stand-offs between officers and their troops.

According to an Associated Press translation, Stoltenberg urged allies not to weaken support for Ukraine, even if the costs are high, because of the increase in energy and food goods prices. The costs of food and fuel are not comparable to those paid by the Ukrainians on the frontline.

Key Background

Due to strong resistance from Ukrainian troops, Russia has shifted its focus to consolidate control of the entire Donbas region, which includes the Donetsk and Luhansk provinces. Russian-backed rebels took control of large parts of the region after the invasion. Russia would control the entire Luhansk province if the key cities were captured.

$5 million. Pentagon spokesman J. Todd Breasseale said in a statement to Forbes last week that the Biden Administration has provided security assistance to Ukraine. A $40 billion spending package was approved by the U.S. Congress last month.

Chief Critic

NATO supports Ukraine, which isn't a member of the alliance but is interested in joining. Even though Ukraine didn't appear to be on the verge of joining NATO, Russia invaded it partly because of that. Russia declared a special military operation to explain to the West that dragging Ukraine into NATO was a criminal act.

The war could last years.

The US is giving a $1 billion military aid package to the Ukrainians.
