Russian President Vladimir Putin's "special military operation" into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered "stiff resistance," according to U.S. officials.
The Russian military has since launched a full-scale ground offensive in eastern Ukraine's disputed Donbas region, capturing the strategic port city of Mariupol and securing a coastal corridor to the Moscow-annexed Crimean Peninsula.

Russia threatens to take 'retaliatory steps' following Finland's NATO announcement

Finland joining NATO would pose threat to Russia, Kremlin says
Russia will conduct a "special analysis" and take necessary measures for national security if Finland joins NATO, Kremlin spokesman Dmitry Peskov said Thursday.
"There is an order from the president, the supreme commander-in-chief, that a list of measures be composed to strengthen our western flanks in connection with the strengthening of the eastern flank of NATO," Peskov told reporters during a daily briefing. "NATO has been enlarging towards us. So, clearly, all of that will be elements of a special analysis and the elaboration of measures necessary for maintaining a balance and providing our security."
"Everything will depend on the manifestation of the further [NATO] enlargement process -- how far the military infrastructure will grow towards our borders," he added.

When asked whether Finland's accession to NATO -- the world's biggest military alliance -- would pose a threat to Russia, Peskov told reporters: "Of course it will."
"Another enlargement of NATO does not make our continent more stable and secure," he said.
Peskov's comments followed a joint statement released by Finnish President Sauli Niinisto and Finnish Prime Minister Sanna Marin announcing their support for Finland applying to join NATO.

Finland says it 'must apply for NATO membership without delay'
Finland's leaders announced Thursday their support for the country applying to join NATO, the world's biggest military alliance.
"During this spring, an important discussion on Finland's possible NATO membership has taken place. Time has been needed to let Parliament and the whole society establish their stands on the matter," Finnish President Sauli Niinisto and Finnish Prime Minister Sanna Marin said in a joint statement. "Time has been needed for close international contacts with NATO and its member countries, as well as with Sweden. We have wanted to give the discussion the space it required."
"Now that the moment of decision-making is near, we state our equal views, also for information to the parliamentary groups and parties. NATO membership would strengthen Finland's security," they added. "As a member of NATO, Finland would strengthen the entire defence alliance. Finland must apply for NATO membership without delay. We hope that the national steps still needed to make this decision will be taken rapidly within the next few days."

The Finnish Parliament will now take up the issue, with a vote expected to be held early next week.
The announcement marks a major shift in Finland's traditionally neutral policy, triggered by Russia's ongoing invasion of Ukraine. Finland shares an 830-mile border with Russia, and recent opinion polls show Finnish public support for joining NATO has surged to 76%.
State Dept. maintains Putin still has 'straightforward' path to peace
Despite President Joe Biden saying Monday that Russian President Vladimir Putin doesn't have a "way out," State Department spokesperson Ned Price insisted the U.S. is providing the Kremlin with a "very simple" and "straightforward" exit strategy through genuine diplomacy.
"The State Department, this administration, provided an off ramp well before President Putin decided to launch this war against Ukraine … it has not closed," Price said.

The problem, Price said, was that Russia continues to show no interest in that route.
Price repeated that one area where the U.S. was not willing to give over any ground was the potential expansion of the NATO alliance.
"NATO's open door means an open door. That is important to us and it is nonnegotiable," he insisted.
