KYIV, May 9 - Russian President Vladimir Putin marked his country’s biggest patriotic holiday Monday without a major new battlefield success in Ukraine to boast of, as the war ground on through its 11th week with the Kremlin’s forces making little or no progress in their offensive.

The Russian leader oversaw a Victory Day parade on Moscow’s Red Square, watching as troops marched in formation and military hardware rolled past in a celebration of the Soviet Union’s role in the 1945 defeat of Nazi Germany, The Associated Press reported.

While Western analysts in recent weeks had widely expected Putin to use the holiday to trumpet some kind of victory in Ukraine or announce an escalation, he did neither. Instead, he sought to justify the war again as a necessary response to what he portrayed as a hostile Ukraine.

“The danger was rising by the day,” Putin said. “Russia has given a preemptive response to aggression. It was forced, timely and the only correct decision.”

He steered clear of battlefield specifics, failing to mention the potentially pivotal battle for the vital southern port of Mariupol and not even uttering the word “Ukraine.”

On the ground, meanwhile, intense fighting raged in Ukraine’s east, the vital Black Sea port of Odesa in the south came under repeated missile attack, and Russian forces sought to finish off the Ukrainian defenders making their last stand at a steel plant in Mariupol.

Putin has long bristled at NATO’s creep eastward into former Soviet republics. Ukraine and its Western allies have denied the country posed any threat.

As he has done all along, Putin falsely portrayed the fighting as a battle against Nazism, thereby linking the war to what many Russians consider their finest hour: the triumph over Hitler. The Soviet Union lost 27 million people in what Russia refers to as the Great Patriotic War.

After unexpectedly fierce resistance forced the Kremlin to abandon its effort to storm Kyiv over a month ago, Moscow’s forces have concentrated on capturing the Donbas, Ukraine’s eastern industrial region.

But the fighting there has been a back-and-forth, village-by-village slog, and many analysts had suggested Putin might use his holiday speech to present the Russian people with a victory amid discontent over the country’s heavy casualties and the punishing effects of Western sanctions.

Others suggested he might declare the fighting a war, not just a “special military operation,” and order a nationwide mobilization, with a call-up of reserves, to replenish the depleted ranks for an extended conflict.

In the end, he gave no signal as to where the war is headed or how he might intend to salvage it. Specifically, he left unanswered the question of whether or how Russia will marshal more forces for a continuing war.

“Without concrete steps to build a new force, Russia can’t fight a long war, and the clock starts ticking on the failure of their army in Ukraine,” tweeted Phillips P. O’Brien, professor of strategic studies at the University of St. Andrews in Scotland.

Nigel Gould Davies, former British ambassador to Belarus, said: “Russia has not won this war. It’s starting to lose it.”

He said that unless Russia has a major breakthrough, “the balance of advantages will shift steadily in favor of Ukraine, especially as Ukraine gets access to growing volumes of increasingly sophisticated Western military equipment.” (ap/ez)
