Russia-Ukraine updates: Putin suspends key US-Russia nuclear treaty in speech denouncing West

President Vladimir Putin said he'd sought an "open dialogue" with the West.

Almost a year after Russian President Vladimir Putin launched a full-scale invasion of neighboring Ukraine, the two countries are engaged in a struggle for control of areas throughout the east and south.

Putin's forces pulled out of key positions in November, retreating from Kherson as Ukrainian troops led a counteroffensive targeting the southern port city. Russian drones have continued bombarding civilian targets throughout Ukraine, knocking out critical power infrastructure as winter sets in.

Putin orders partial military mobilization, issues nuclear threat

Russian President Vladimir Putin has ordered a partial mobilization of reservists in Russia, in an apparent admission that his war in neighboring Ukraine isn't going according to plan.

In a seven-minute televised address to the nation that aired on Wednesday morning, Putin announced the start of the mobilization -- the first in Russia since World War II. The measure is expected to draft more than 300,000 Russian citizens with military experience, according to Russian Defense Minister Sergei Shoigu.

The move comes as Moscow is poised to annex all the regions it occupies in Ukraine in the coming weeks, with plans to hold sham referendums this weekend in an effort to politically legitimize its actions. By declaring those areas officially Russian territory, Putin is also threatening that any continued efforts by Ukraine to retake them will be seen as a direct attack on Russia. In his speech Wednesday, the Russian leader raised the specter of using nuclear weapons if Ukraine continues to try to liberate the occupied regions.

"In the event of a threat to the territorial integrity to our country, for the protection of Russia and our people, we of course will use all means in our possession," Putin said. "This is not a bluff."

"Those who are trying to blackmail us with nuclear weapons should know that the wind can turn in their direction," he added.

It's an attempt to regain the initiative after disastrous setbacks in Russia's war against Ukraine.

Russia has been suffering severe manpower shortages in Ukraine after months of heavy losses, mainly because the Kremlin has pretended it is fighting not a war but a "special military operation." That, in part, allowed Ukraine's spectacular counteroffensive in the country's northeast two weeks ago, which led to the collapse of Russia's frontline there.

Military experts and Russian commentators themselves had acknowledged that without a mobilization, Moscow is not capable of anymore offensive operations in Ukraine and in the longterm might well be unable to even hold the territory it has already taken.

Putin has balked at ordering a mobilization, until now, because of the huge political risks it carries for him at home. Russians have proved relatively supportive of the war while they have not been ordered to fight it, but this carries much bigger risks now of domestic unrest. It will bring up dangerous memories of the Soviet disaster in Afghanistan and Chechnya.

Yet Putin has clearly decided he must take the risk, with losing the war in Ukraine seen as an existential danger to his regime.

The mobilization order has profound implications for not just Russia and Ukraine, but also for Europe and the United States. It means Putin is expanding the war in Ukraine even further, ready to throw hundreds of thousands more people into it -- making the fight harder again for Ukraine, while also raising the threat of nuclear strikes on it. And at home, Putin is going to enter uncharted waters.

US and Ukraine bolster efforts to prosecute Russia for war crimes

U.S. Attorney General Merrick Garland met Tuesday with Ukrainian Prosecutor General Andriy Kostin and signed a memorandum of understanding to strengthen their investigative partnership in pursuing prosecutions against Russians accused of committing war crimes in Ukraine.

"America and the world have seen the horrific images and the heart-wrenching reports of the brutality and death caused by the unjust Russian invasion of Ukraine," Garland said following the meeting at the Department of Justice in Washington.

Garland said the DOJ's War Crimes Accountability Team has provided Ukraine with a "wide variety" of technical assistance on criminal cases, including collecting evidence and forensic analysis.

The memorandum of understanding, Garland said, will allow the two countries to "work more expeditiously and efficiently" in their investigations of Russian war crimes.

Kostin also delivered somber remarks on war crimes uncovered by Ukrainian investigators since the start of the Russia's invasion. He said that two hours before his meeting with Garland, a prosecutor in the Kharkiv region of Ukraine informed him of a village "where about 100 graves" were just discovered.

"This place is not safe at the moment since it needs de-mining," Kostin said. "But this is a new example of mass atrocities by the aggressor. This is a sign that Russia uses not only prohibited means and methods of warfare, but this is a clear and intentional policy of Russia."

Ukraine conflict could increase food prices, food insecurity: Study

The impact on crop production due to Russia's invasion of Ukraine will likely continue to increase global food prices and food insecurity, though not as much as initially feared, according to a new study.

The price of corn and wheat are expected to increase by 4.6% and 7.2%, respectively, and crops such as barley, rice, soybeans and sunflower are also anticipated to rise, according to a study from Indiana University published this week in Nature Food.

Nations with current existing food insecurity will be most impacted by the conflict, according to the study.

Other countries, including Brazil, have stepped up their production to fill the gap left by the lack of exports coming out of the region, offsetting some of the impacts on world food prices and food insecurity, the study found. Clearing more land and vegetation to grow crops could increase deforestation and carbon emissions, the study said.

White House slams referendums in Russia-backed regions of Ukraine

U.S. national security adviser Jake Sullivan said referendums planned for this week in Russia-backed areas of eastern and southern Ukraine are a "sham."

"Russia is throwing together sham referendums on three days notice as they continue to lose ground on the battlefield and as more world leaders have distanced themselves from Russia on the public stage," Sullivan said in a briefing Tuesday at the White House.

He also slammed legislation being pushed through the Russian parliament to lay the ground for a general mobilization of men aged 17-27 as "scraping for personnel to throw into the fight."

“These are not the actions of a confident country. These are not acts of strength, quite the opposite," Sullivan said. "We reject Russia's actions unequivocally."
