US National Security Adviser Jake Sullivan has promised that there would be “catastrophic” consequences if Russia used a nuclear weapon in Ukraine.

“If Russia crosses this line, there will be catastrophic consequences for Russia. The United States will respond decisively,” he told NBC.

“Now in private channels, we have spelled out in greater detail exactly what that would mean.”

Sullivan also said the US will enact further economic sanctions against Russia if the Kremlin completes its “sham” referendums in occupied territories of Ukraine.

He pointed to the Group of 7 leaders’ statement from Friday and said there will be more announcements from the Biden Administration in the days ahead.

“They reiterated that there would be consequences and specified that that would include additional enhanced sanctions, including sanctions on entities and companies outside of Russia that are supporting the Russian war machine or supporting these fake referenda or Russia’s efforts,” Sullivan said.

Asked about ongoing protests in Russia, Sullivan said the US is focused on continuing to support Ukraine: “The future of Russia is for the Russian people to decide.”

British PM: Putin has been ‘outsmarted’

Vladimir Putin’s announcement of increased military conscription to bolster Moscow’s invasion of Ukraine shows that the Russian president “has been outsmarted” by Kyiv, UK Prime Minister Liz Truss told CNN.

The new British leader, who takes power at a time of historic upheaval, said that Putin had ordered an immediate military escalation “because he isn’t winning”.

“He made a strategic mistake, invading Ukraine,” Truss said in her first interview with a US network, which aired on Sunday.

“I think he has been outsmarted by the Ukrainians.

“We’ve seen the Ukrainians continue to push back against the Russian offensive.

“And I think he didn’t anticipate the strength of reaction from the free world.”

Last week Russian Defence Minister Sergei Shoigu said the country would summon 300,000 reservists, following a sweeping offensive from Kyiv this month that has spurred Ukraine’s Western allies and provoked anger in Russia.

Rock legend’s shows scrapped over stance on war

Concerts planned in Poland next year for rock legend and Pink Floyd co-founder Roger Waters have been cancelled amid backlash to the musician’s stance on Russia’s invasion of Ukraine.

Live Nation Poland, the concert’s promoter, confirmed the cancellation on Saturday without giving a reason.

“A town councillor in Krakow, a Mr Łukasz Wantuch has threatened to hold a meeting asking the council to declare me ‘Persona non grata’ because of my public efforts to encourage all involved in the disastrous war in Ukraine, especially the governments of the USA and Russia, to work towards a negotiated peace, rather than escalate matters towards a bitter end that could be nuclear war and the end of all life on this planet,” Waters said in a statement on Facebook on Sunday.

Waters penned a controversial open letter earlier this month to Ukrainian first lady Olena Zelenska, where he stated his opposition to the West sending weapons to Ukraine to aid the embattled country in its war against invading Russia.

Waters also accused Ukrainian President Volodymyr Zelenskyy of doubling back on his 2019 election campaign promises and said, without offering proof, that “the forces of extreme nationalism that had lurked, malevolent, in the shadows, have, since then, ruled the Ukraine”.
