Biden Says Putin Has Chosen ‘Catastrophic’ War Over Diplomacy

WASHINGTON — President Biden said on Friday that the United States has intelligence showing that President Vladimir V. Putin of Russia has made a final decision to reject diplomatic overtures and invade Ukraine, in what Mr. Biden said would be a “catastrophic and needless war of choice” in Eastern Europe.

Speaking from the Roosevelt Room in the White House, Mr. Biden said “we have reason to believe the Russian forces are planning to and intend to attack Ukraine in the coming week, in the coming days,” adding that “we believe that they will target Ukraine’s capital, Kyiv, a city of 2.8 million innocent people.”

Asked whether he thinks that Mr. Putin is still wavering about whether to invade, Mr. Biden said, “I’m convinced he’s made the decision.” Later, he added that his impression of Mr. Putin’s intentions is based on “a significant intelligence capability.”

Still, Mr. Biden implored Russia to “choose diplomacy.”

“It is not too late to de-escalate and return to the negotiating table,” Mr. Biden said, referring to planned talks between Secretary of State Antony J. Blinken and Russia’s foreign minister on Thursday. “If Russia takes military action before that date, it will be clear that they have slammed the door shut on diplomacy.”

In the hours before Mr. Biden’s late afternoon remarks, Russia-backed separatists in eastern Ukraine called for mass evacuations in two contested regions of the country, claiming, with little evidence, that Ukraine’s military was about to launch a large-scale attack there, an assertion that appeared intended to provoke Russian military intervention.

The ominous messaging of the rebels in the regions of Donetsk and Luhansk was loudly echoed by Moscow, raising fears that Russia was setting the stage for an imminent invasion that could ignite the biggest conflict in Europe in decades.

The call by the Russian-backed separatists for evacuations came as they blamed Ukraine for an array of provocations, including shelling along the front lines between Ukraine and the separatist forces, and an explosion involving an empty car that pro-Moscow news outlets said belonged to the head of the region’s security services.

Mr. Biden, who had just concluded a video call with a dozen Western leaders, rejected the claims as lies intended by Mr. Putin to inflame the situation on the ground and provide a pretext for war — something the United States and other European leaders had been warning about for weeks.

He cited the bombing of a Ukrainian kindergarten as a Russia-backed provocation. And he pointed to Russian separatist accusations that Ukraine was planning to launch a major offensive attack as evidence of Russian efforts to justify military action with misinformation.

“There is simply no evidence to these assertions, and it defies basic logic to believe the Ukrainians would choose this moment, with well over 150,000 troops arrayed on its borders, to escalate a yearlong conflict,” Mr. Biden said.

The president’s comments are the clearest indications of just how close the world may be to the largest conflict in Europe since World War II. He took the highly unusual course of specifically predicting the time frame and parameters of the invasion, despite the risks that he could be proved wrong.

“We’re calling out Russia’s plans loudly and repeatedly,” Mr. Biden said. “Not because we want a conflict but because we’re doing everything in our power to remove any reason that Russia may give to justify invading Ukraine and prevent them from moving.”

The president did not say how the administration knew about Mr. Putin’s decision, but two U.S. officials said the president’s assessment was based in part on new intelligence showing that nearly half of the 150,000 Russian forces have moved out of staging and into combat formation and could launch a full-scale invasion within days.

The force includes 120 to 125 battalion tactical groups, up from the mid-80s earlier in the month. And some of the forces are Russian reservists who would make up an occupation force after an invasion, the officials said. The officials asked for anonymity to discuss government assessments.

Mr. Biden vowed that the United States and its allies were united behind imposing severe economic sanctions if Russia’s forces cross Ukraine’s borders. He said he also held a call with Democratic and Republican lawmakers who expressed united support for the administration during a visit to Munich for a security conference.

In Ukraine, the head of the country’s Ministry of Defense said the claim of an imminent attack by its military was categorically false and intended to inflame tensions. But the ministry issued a stark warning to residents of the contested regions “not to leave their homes and not to use public transport.” It cited “information that Russian special services have mined a number of social infrastructure facilities in Donetsk,” with the aim of “destabilizing the situation” there.

The warning reflected how Russia appeared to be pulling out all the stops to pressure the Ukrainians short of sending its troops across the border.

The fears of brewing conflict were reinforced as U.S. officials said that as many as 190,000 troops and aligned militias were arrayed in and near Ukraine, a number that includes the separatists. The assessment was delivered in a statement by the U.S. mission to the Organization for Security and Cooperation in Europe, which called it “the most significant military mobilization in Europe since the Second World War.”

Consistent with Russia’s contradictory messaging throughout the crisis, however, Mr. Putin said on Friday that he was prepared for further diplomacy. The announcement of the meeting between Mr. Blinken and the Russian foreign minister, Sergey V. Lavrov, calmed jittery markets and suggested that there was still hope for the crisis to be resolved without war.

But Mr. Putin emphasized that Russia would continue to insist on far-reaching demands for “security guarantees” in Eastern Europe that the West has rejected — such as a halt to the eastward expansion of NATO and the pullback of the alliance’s forces from the region.

“We are ready to go on the negotiating track under the condition that all questions will be considered together, without being separated from Russia’s main proposals,” Mr. Putin said in a news conference alongside his close ally President Aleksandr G. Lukashenko of Belarus, who was visiting Moscow.

Friday’s drumbeat of alarms from the separatists about Ukrainian provocations aligned with how Western officials have been warning that a “false flag” incident could be used to start a military conflict.

In calling for people in the contested areas to evacuate to Russia, Denis Pushilin, the pro-Moscow leader of the Donetsk People’s Republic, offered a stark version of what might be coming in citing supposed provocations by Ukraine.

“Very soon, President of Ukraine Volodymyr Zelensky will order the military to go on an offensive, to implement a plan to invade the territory of Donetsk and Luhansk people’s republics,” he said in a video posted online, offering no evidence.

Kyiv firmly denied Moscow’s accusations. And in his remarks Friday, Mr. Biden said there was “no evidence” behind them.

Although Moscow insists that it has no plans for an invasion, it has vowed to mount “a tough response” if the United States and its NATO partners do not roll back their presence in Eastern Europe.

In a demonstration of strength, Russia plans major drills this weekend that will include the launch of ballistic and cruise missiles, the country’s Defense Ministry said, according to the Interfax news agency.

Russia’s drills will test its strategic nuclear forces, which include the land-based launchers, bombers and warships used to deliver nuclear weapons. They will involve the Black Sea Fleet, which has been engaged in large-scale exercises in the region bordering Ukraine. Mr. Putin will preside over them from a “situation center,” the Kremlin said.

The Defense Ministry said the drills had been planned in advance, and Dmitri S. Peskov, Mr. Putin’s spokesman, denied that they were intended to raise tensions with the West. But they will come at a critical juncture in the standoff over Ukraine.

Near the front in Ukraine, it was possible to hear the blasts from munitions fired by the Ukrainian military and incoming fire from the pro-Russian separatists.

A total of 12 houses were damaged by shelling Friday morning, said a local branch of the United Nations High Commissioner for Refugees.

In remarks before Ukraine’s parliament, the country’s defense minister, Oleksiy Reznikov, urged Ukrainians living in the separatist-held territory not to believe Russian propaganda that the Ukrainian government was going to attack them.

“Don’t be afraid,” he said. “Ukraine is not your enemy.”

An estimated 3.5 million people live in the two breakaway regions, and self-declared republics, and since the war started there, Russia has handed out citizenship to more than 700,000 people living in the Donbas region. In his messaging on Ukraine, Mr. Putin has warned of the plight of ethnic Russians in the country, saying that events in eastern Ukraine “resemble genocide.”

Highlighting the growing risk of military conflict, Britain announced Friday night that it was following the United States’ lead in evacuating its embassy from Kyiv to the western city of Lviv.

With fears running high that Russian troops in Belarus could invade Ukraine from the northern border with Belarus, only 140 miles from the capital, the Ukrainian authorities ordered the site of the Chernobyl nuclear disaster closed to tourists.
