For Ukrainians whose lives have been upended by war, Kursk offensive is a morale boost

Ukraine's swift entryinto Russia's Kursk region caught Moscow by surprise, as Kyiv's forces quickly took control of a swath of the border oblastand put their opponenton the defensive.

The pace of Ukraine'sgains has sinceslowed, but not stopped,as Kyiv'stroops have hitbridges, capturedRussian conscriptsand forced Moscowto deal with an unanticipatedattack now in its third week.

And for Ukrainians,whose lives have been upended by 30 months of all-out war with Russia, the audaciouspush has buoyed their hopes. Yet this optimism is tempered by concerns about how events could stillturn and not necessarily in Ukraine's favour.

"The public sees the operations in Kursk as a much-needed boost morale is up, there's a sense of hopeand immense pride that we can push Russia back, even in their own territory," Tymofiy Mylovanov, an economist and former Ukraine government minister, said via email, from Kyiv.

"However, there are two main concerns: whether we can hold these gains and the real cost in Ukrainian lives."

A surprise even to Ukrainians

The Kurskoffensive came as a surprise evento Ukrainians, as they watched their armed forcesundertake the largest attack on Russia since the Second World War.

"I have to emphasize that this operation was kept in complete secret," said Yevheniia Kravchuk, a Ukrainian lawmaker and a member of Ukrainian President VolodymyrZelenskyy's Servant of the People political party.

Kravchuk said Ukrainians have gradually learned more about the Kursk offensive, which began on Aug.6, and she believes it has provided an "exceptional boost" to the mood of soldiers and civilians alike.

Anton Kuchukhidze, co-founder of the United Ukraine think-tank,said Ukrainians are proud of their soldiers and what they are doing for their country in Kursk and elsewhere.

But he also said Ukrainians "are realists" who are living through war themselves and arefully aware of everything their soldiers are up against.

"All of us understand that the war is not finished," Kuchukhidze said.

Andriy Kulykov, a Kyiv-based journalist and chairof Ukraine's Hromadske Radio, saidthe public reaction to the Kursk offensivehas been positive, perhaps partly because "people were starved of reports of military success."

However, Oleksiy Goncharenko, afellow Ukrainianlawmaker who hails from Odesa, sees a broader range of opinions being expressed.

"Some Ukrainians understand and support this operation, some do not. This is a democracy, so everyone has their own opinion," he told CBC News in an emailed statement.

"But we believe in our armed forces," he said, noting thatUkraine's parliament has voted to provide additional support for those fighting in the Kursk region.

Those divided opinionscan be foundon the streets of Kyiv.

"We don't know to what this will lead to, but we all have our hopes high," OlhaPavlovska, a resident of the capital, told Reuters.

Veteran Yaroslav Mandel, meanwhile, told the news agency that the Kursk offensive amounted to"a show" compared to what soldiers in eastern Ukraine are dealing with.

Viktor Kovalenko, a fellowUkrainian combat veteran who lives in the United States, saidhe found the news from Kursk hard to absorb at first, but he then became "cautiously optimistic" about what was unfolding though he still has concerns about where things could go.

Ukrainian push into Russia is 'catastrophic' for Putin's plans, former U.S. ambassador says

Wider threats toUkraine

The pressure that Ukraine has put on Russia in the Kursk region has not diminished the problems it faces along other parts of its border includingin eastern Ukraine, where Russia has made slow and grinding gains in recent months.

There hasalso been some suggestion that Russia might be compelled to shift some of its troops from Ukraine's eastern regionto deal with the situation inKursk. This does not appear to have been the case so far.

"The initial expectations that the offensive may distract substantial Russian forces from the front line in Donetsk oblast do not seem to materialize,"Kulykov, the Kyiv-based journalist, saidin an email.

However, some key goals of Ukraine's offensive as spelled out by Kyiv include establishing a "buffer zone" in Kursk to prevent Russian attacksand capturing Russian soldiers,who can be exchanged for Ukrainian prisoners of war.

Kravchuk, the Ukrainian lawmaker,said the return of Ukrainian PoWs is a politically sensitive issue and one on which she feels pressure from constituents.

"They expect that we can exchange our prisoners of war that are still ... in captivity in Russia," she said.

'Real leverage' for Ukraine?

Ukraine's president has stated it's critical that the country strengthen its position ahead of the fall.

Mylovanov, the former government minister, said he believes the Kursk action gives Ukraine "real leverage," no matter what Moscow may be saying about it.

"Russia, and particularly Putin, are trying to downplay the significance of Kursk to limit our leverage," he said, referring to Russian President Vladimir Putin."They've learned the hard way that they can't push us back quickly."

Mylovanov noted that a fierce Russian retaliationover Kurskcould be a risk, as could a lessening of U.S. support though he said neither seemed likely at the moment.

With a looming U.S. election, there could be implications for Ukraine in terms of futuresupport from Washington with one of the main presidential contenders, Donald Trump, having repeatedly claimed he'll settle the conflict.

Kovalenko, who served in Ukraine's military a decade ago, said he believes Kyiv is trying to do what it can to be ready for eventual negotiations with Russia and it should decide the timing for that on its own.

"Do not force Ukraine to make a deal now," he said.
