Putin, Scholz agree on need to avert war amid Ukraine tensions******
Russian President Vladimir Putin (right) and German Chancellor Olaf Scholz give a joint press conference following their meeting over Ukraine security at the Kremlin, in Moscow, on February 15, 2022.
Both Russian President Vladimir Putin and visiting German Chancellor Olaf Scholz on Tuesday underlined the need to avoid a war over Ukraine and to settle the crisis via diplomatic efforts.
"Regarding whether we want this (war), of course we don't. This is why we have put forward proposals for the start of a negotiation process in a bid to reach an agreement ensuring equal security for everyone," Putin said during a press conference with Scholz following their talks in the Kremlin.
Scholz said despite that the positions of the North Atlantic Treaty Organization (NATO) and the European Union may differ from those of Russia, dialogue remains crucial.
Europe is faced with one of its most dangerous crises in decades and there is an urgent need to defuse the tensions regarding Ukraine and prevent a possible war, the German leader stressed.
As a war in Europe is "unimaginable," Scholz considered it the duty of both Putin and himself to prevent any military escalation on the continent.
"Diplomatic opportunities have not yet been exhausted ... We have heard that some (Russian military) units are being withdrawn (from the borders) and this is a good sign," Scholz said.
As for Russia's security concerns, Scholz assured Putin that NATO's expansion is not even on the agenda.
However, Putin said that postponing Ukraine's possible accession to NATO will resolve nothing for Russia, and Moscow wants its security concerns to be addressed seriously.
Russia will act "in accordance with the plan" and its moves will reflect the latest realities, but no one can predict how the situation will unfold, Putin said, adding that Moscow, nevertheless, will strive to resolve all the existing issues by diplomatic means.
Defiant Biden touts first year, vows to reconnect with voters******
US President Joe Biden answers questions during a news conference in the East Room of the White House on January 19 in Washington, DC.。
Joe Biden sought to reset his presidency in a marathon first year press conference on Wednesday, vowing to reconnect with voters and touting successes, while delivering blunt assessments of the "disaster" facing Russia if it attacks Ukraine.。
"Can you think of any other president that's done as much in one year?" Biden asked, ticking off the epic struggle against COVID-19 and trillions of dollars in government funding to save the US economy from pandemic fallout.。
"I don't think there's been much on any incoming president's plate that's been a bigger menu than the plate I had given to me," the Democrat said. "The fact of the matter is, we got a lot done."
Speaking on the eve of the anniversary of his inauguration on January 20, 2021, Biden held only the second White House press conference of his presidency – then surprised many by staying at the podium for one hour and 52 minutes.。
The exchange, according to US media, extended beyond even the longest of the famously rambling – though far more frequent – press conferences held by Donald Trump.。
At various times combative, joking and meandering, Biden rejected criticism over his handling of the pandemic and soaring inflation.。
Asked about his approval ratings, which have sunk into the low 40 percent area, Biden was curt.。
"I don't believe the polls," he said.。
Biden acknowledged missteps since taking over from Trump, citing "a year of challenges."
These included that he "didn't anticipate" the ferocity of Republican obstruction to his agenda in Congress.。
On COVID-19 testing capabilities, which continue to struggle to meet demand, he said "we should have done it quicker."
Biden likewise said he understood "frustration" over steadily rising prices, which he blamed on COVID-related supply chain issues.。
Fighting inflation will be "hard and take a lot of work."
"It's going to be painful for a lot of people," he said, noting that high prices were being felt "at the gas pump, the grocery stores and elsewhere."
On one of the most traumatic episodes of his presidency – the chaotic and rushed final withdrawal from the 20-year long Afghanistan war – Biden said flatly: "I make no apologies."
"There was no way to get out of Afghanistan after 20 years easily," he declared.。
The press conference, which defied the widely shared image of Biden as shrinking from contact with the media, focused especially heavily on the looming crisis in Ukraine, where the United States is leading Western efforts to find a diplomatic solution to Russia's military posturing on the border.。
Biden said he was ready to meet with Putin and bluntly warned the Kremlin leader that an attack on Ukraine would be "a disaster" for Russia.。
However, Biden raised eyebrows when he appeared to suggest that a small-scale attack by the Russians would prompt much less pushback from the West.。
The White House quickly issued a statement clarifying that what he meant was that any military invasion would prompt a "severe" response, while non-military aggression, like paramilitary attacks, would be met with a "reciprocal" response.。
Powerful Republican Senator Lindsey Graham described Biden's comment as "unnerving."
With a State of the Union speech to Congress set for March 1, Biden faces a diminishing period to engineer a strategy to fight off a Republican comeback at midterm congressional elections this November.。
Republicans are forecast to crush his party and take control of the legislature.。
That risks bringing two years of complete obstruction from Congress, likely including threats of impeachment and a slew of aggressive committee probes.。
Trump, who continues to perpetuate the lie that he beat Biden in 2020 and seeks to undermine Americans' faith in their election system, is eying an attempt at another presidential run in 2024.。
Biden confirmed he would keep Kamala Harris as his vice presidential running mate in a reelection bid.。
And he said that while Democrats proved unable to use their razor-thin congressional majority to pass two big priorities – the Build Back Better social spending bill and election law reforms – they could instead settle for passing "big chunks" of the legislation.。
A reminder of that failure was coming later Wednesday evening when the Senate was all but certain to block the voting rights reforms.。
Above all, Biden emphasized his desire to leave the confines of the White House after a year featuring a decidedly light travel schedule.。
"Number one: I am getting out of this place more often. I am going to go out and talk to the public," he said.。
"I find myself in a situation where I don't get a chance to look people in the eye, both because of COVID and the situation in Washington," he said, describing how he wanted to "connect with people, let them take a measure of my sincerity."
