The invasion of Ukraine has serious, unintended consequences for Russia. Here are just 5 of them

When Russia invaded Ukraine, it was widely believed to have expected an easy victory over its neighbor.

But so far, Russia has little to show for what it has called its "special military operation": Its forces have been bogged down in fighting mainly on the northern, eastern and southern fringes of Ukraine and have found the country to be much more organized and well equipped than they expected.

Russian forces have seized only one city, Kherson, but even that occupation looks shaky, with Ukrainian forces launching a counteroffensive to retake the southern port. Similar moves have been seen elsewhere in Ukraine, with officials claiming its forces are mounting an increasing number of counterattacks.

Just over a month into the war, Moscow is facing unintended consequences of its aggression in Ukraine, ranging from high casualties among its troops to economic ruin for years to come.

Here are five of them:

Russia has been coy about releasing statistics on its losses, but one Russian Defense Ministry official said Friday that 1,351 Russian soldiers had died in the war so far, and that 3,825 were injured.

Ukraine's authorities claim that more than 15,000 Russian soldiers have been killed in the conflict, while a senior NATO official last week estimated that between 8,000 and 15,000 have been killed.

If accurate, those numbers would be a heavy death toll for Russia — comparable to the almost 15,000 Soviet soldiers who died during the 10-year war in Afghanistan in the 1980s. To this day, that incursion is unpopular in Russia because it gained the country little but cost much blood.

To put the Russian forces' casualties in context, the United Nations' human rights office (OHCHR) said Tuesday that it has recorded a total of 1,151 deaths among Ukrainian civilians, including 54 children, and more than 1,800 injured civilians. It believes that the actual casualty figures are considerably higher.

"Most of the civilian casualties recorded were caused by the use of explosive weapons with a wide impact area, including shelling from heavy artillery and multiple launch rocket systems, and missile and air strikes," the OHCHR said.

One of the likely consequences of this war is that many Ukrainians will harbor an abiding animosity toward Russia, particularly after the bombing of homes and civilian infrastructure — including a children's hospital and maternity ward in Mariupol, as well as a theater where families were seeking shelter. These are widely seen as war crimes by the international community. Russia claims it has not targeted civilians.

Ukrainian President Volodymyr Zelenskyy summed up the mood in the country in early March when he stated that "we will not forgive, we will not forget, we will punish everyone who committed atrocities in this war on our land," before adding that "there will be no quiet place on this Earth except the grave."

Russian President Vladimir Putin has extolled the cultural, linguistic and historical ties between Russia and Ukraine, but he's driven what's likely to be a permanent wedge between the nations.

One member of the Ukrainian parliament, Kira Rudik, tweeted Monday that seeing Ukrainian homes burning as a result of Russian attacks "just makes us feel more rage" while another joined calls for reparations of $400 billion from Russia in order to rebuild Ukraine.

Putin has goaded Ukrainians in recent years, reiterating his belief that Ukraine is not "even a state" and that it's a historical part — and indeed a creation — of Russia, a claim he's made again in recent weeks.

Many Ukrainians, on the other hand, have spent much of the last two decades trying to assert its separateness from Russia, rejecting pro-Russian politics (and politicians) and instigating not one but two dramatic uprisings in 2004 and 2013. In the latter "Euromaidan" protests, thousands of Ukrainians braved police brutality and violent repression to call for political change, and for Ukraine to join the EU.

This ambition has only deepened under President Zelenskyy, who has asked the EU to fast-track Ukraine's accession to the bloc, while conceding that Ukraine might never join NATO — one of Moscow's intended consequences — as it looks to compromise in order to find a peace deal with Russia.

The international community was accused of being slow and ineffective when Russia annexed Crimea from Ukraine in 2014. This time, it upped the ante when Russia's full-scale invasion began, with Western democracies imposing wide-ranging sanctions on key Russian sectors, businesses and individuals connected to the Kremlin or who support the invasion.

As a result, the Russian economy is expected to fall into a deep recession this year. The Institute of International Finance predicts Russia's economy will contract by as much as 15% in 2022 because of the war. It also predicted a decline of 3% in 2023 and warned in a note last week that the war "will wipe out fifteen years of economic growth."

Analysts at TS Lombard predict Russian citizens will experience a "serious hit" to living standards from the combination of recession and high inflation. The annualized inflation rate stood at 9.2% in February and is expected to have risen markedly higher in March, and there is "a plausible end-year range of 30-35%," Christopher Granville and Madina Khrustaleva said in a note Monday.

This, they added, may have important medium- to longer-term consequences, especially on a political level, with Putin's popularity likely to be tested as a result. They did, however, note one way Russia can mitigate the impact of sanctions on its economy: boosting its oil exports to China and India. Russia's oil-producing allies in OPEC are also standing by it.

The war has also accelerated Europe's transition away from Russian energy imports, putting a large dent in the revenues Russia receives from energy exports.

It has also made the $11 billion Nord Stream 2 gas pipeline — designed to bring more Russian gas to Europe (and which the United States, Poland and Ukraine warned would increase the region's energy insecurity) — redundant, perhaps for good.

Experts think Putin likely expected his invasion of Ukraine to have a disunifying effect on the West, with countries unable to agree on sanctions, or sending arms to Ukraine, but the opposite has proven true.

"The West's reaction is unprecedented. It is beyond anyone could have anticipated — united and much more than anyone in Russia was preparing or prepared for," Anton Barbashin, a political analyst and editorial director of the journal Riddle Russia, told CNBC.

"Essentially it is the ultimate economic warfare that will destroy Russia's economy as we know [it]. Will those sanctions deter Putin's war in Ukraine – no, but it will certainly considerably limit the time we have with Putin's Russia as it is today," Barbashin added.
