NATO Secretary-General Jens Stoltenberg said Russian President Vladimir Putin still wants to capture all of Ukraine, despite repositioning forces to the eastern Donbas region.
"We have seen no indication that President Putin has changed his ambition to control the whole of Ukraine and also to rewrite the

Russian forces will likely launch a "concentrated" offensive in the Donbas region in the coming weeks, Stoltenberg previously said, after moving a significant portion of troops away from Kyiv.
Ukraine has been fighting Moscow-backed rebels in the Donbas region since 2014, when Putin's forces annexed Crimea.
The region became a key focus in recent months during the buildup to the current war, where Russia staged pretexts to try and justify an invasion of Ukraine.
Stoltenberg also said on Wednesday that Putin wants to control all of the Donbas, and establish a land bridge between the region and Russia.
"We need to support Ukraine, sustain our sanctions, and strengthen our defenses and our deterrence because this can last for a long time and we need to be prepared for that," Stoltenberg said.
Stoltenberg's remarks echoed those of US Gen. Mark Milley, chairman of the Joint Chiefs of Staff, who told Congress on Tuesday that the war could last years.
"There is much of the ground war left in Ukraine, but I do think this is a very protracted conflict. And I think it's at least measured in years," Milley told the House Armed Services Committee.
Angela Stent, a Georgetown professor and top Russia expert, last week told Insider that Putin will never "give up on Ukraine" as long has he's in the Kremlin.
"He is not going to give up on his goal of subordinating Ukraine" and "having a government there that's pro-Russian," said Stent, who served as national intelligence officer for Russia and Eurasia at the National Intelligence Council from 2004 to 2006.
"They may be focusing now on the Donbas, but I don't think anybody believes that they've completely given up taking Kyiv," Stent added, underscoring that Putin has for years been "obsessed" with the goal of subjugating all of Ukraine.
Putin over the years has repeatedly suggested that Ukraine is not a real country, and referred to Ukrainians and Russians as "one people." The Russian leader has frequently signaled that he believes Ukraine should be under Moscow's control.
In the days leading up to Russia's unprovoked invasion, Putin offered a revisionist history as he laid out the justifications for his aggression toward Ukraine.
"Ukraine has never had its own authentic statehood. There has never been a sustainable statehood in Ukraine," Putin said, pushing the false notion that Ukraine never would've existed without the Soviet Union and portraying it as part of Russia's historic territory.
