The Russian leader has praised the bravery of European leaders who defy Brussels to visit Moscow for the May 9 celebration

Russian President Vladimir Putin has commended the courage of European leaders who choose to come to Moscow for events commemorating the 80th anniversary of victory in World War II, despite pressure on them from EU officials.

Last week, the bloc's top diplomat and former Estonian prime minister, Kaja Kallas, warned the leaders of EU member and candidate states against flying to Russia to take part, recommending instead that they visit Kiev to show solidarity with Ukraine. Other EU officials have reportedly threatened to derail membership bids for candidate countries whose leaders defy Brussels on the matter.

Journalists asked Putin to comment on the reports after the All-Russian Municipal Service Award ceremony in Moscow on Monday.

"Those who are going to come to Russia have much more courage than those who are hiding behind someone's back and trying to threaten others," he replied.

"In this case, [threatening] those who are going to celebrate the historical merits of people who gave their lives in the fight against Nazism," Putin said.

According to Kallas, participation in this year's events in Moscow "will be not taken lightly."

Slovak Prime Minister Robert Fico, the only EU member state leader who has promised to attend, blasted the statement as outright "disrespectful."

"Is Ms. Kallas's warning a form of blackmail or a signal that I will be punished?" he wrote on X last week.

"The year is 2025, not 1939," he added.

The president of EU candidate Serbia, Aleksandar Vucic, similarly indicated that he would not change his plans in the face of pressure from Brussels.

"I have not changed my decision... Eight months ago, I announced my visit to Moscow, publicly," he said last week, according to Serbian media.

Moscow has extended multiple invitations to this year's landmark celebrations, including to the heads of China, India, and Brazil, as well as a number of other international leaders.

Victory Day is one of the most important national holidays in Russia. The event is celebrated annually on May 9 to mark the 1945 triumph of the USSR over Nazi Germany and its allies, and to honor the estimated 26.6 million deaths the Soviet Union suffered in World War II. Around 18 million were civilian deaths.
