Paris: Russia’s attack on Ukraine on February 24 shocked the world but President Vladimir Putin shows no sign of pulling back.
Here are possible scenarios for the weeks and months ahead, according to Western government sources and think-tank experts.
Ukrainian forces have resisted Russia’s attack so far, defeating an attempt by paratroopers to seize the capital in the opening days and keeping control over major cities such as Kharkiv and Mariupol.
Although Russia claims it has full air superiority, Ukraine’s air defences around the capital Kyiv and in other areas appear to be degraded but still working, Western officials say.
“That’s caused them so many problems,” a European source told reporters on Friday on condition of anonymity.
Vast numbers of Ukrainians have also joined territorial defence units and there remain questions about the morale of the Russian army and its logistical support.
Backed by Western intelligence and a flow of anti-tank and surface-to-air missiles, Ukraine’s troops might be able to hold out in the capital and force some sort of military stalemate.
Deepening Western sanctions that are strangling the Russian economy might force Putin to change his calculations.
“The West could leverage some sanctions to push Putin to abandon his core war aim of decapitating the Ukrainian government and installing a pro-Russian puppet,” wrote Samuel Charap from the RAND Corporation, a US think-tank, this week.
Domestic Russian change
Small anti-war demonstrations have taken place in cities from Saint Petersburg to Moscow.
Some oligarchs, MPs, and even private oil group Lukoil are calling openly for a ceasefire or an end to fighting.
Russian military success
Given Russian troops’ superior weapons, air power and devastating use of artillery, Western defence analysts expect them to continue grinding forward.
A huge convoy of vehicles has been assembled outside of Kyiv ahead of what is expected to be an assault on the capital.
French President Emmanuel Macron concluded that “the worst is still to come” after a call with Putin on Thursday morning.
Putin wants “to seize control of the whole of Ukraine”, an aide told reporters afterwards.
But even if Russian troops depose Ukrainian President Volodymyr Zelensky and overrun Ukraine’s resistance elsewhere, Putin would then face the challenge of occupying a nation of 40 million.
“Getting into a city is not the same as holding it,” wrote British warfare historian and King’s College London professor Lawrence Freedman on Substack this week.
Ukraine has a border with four former Soviet states that are now members of the US-led Nato military alliance, which considers an attack on one member to be an attack against all.
“Neutral Sweden is keeping a watchful eye on Russia’s intentions towards the Gotland island in the Baltic Sea,” wrote analyst Bruno Tertrais for the Montaigne Institute, a French think-tank.
Charap warned of the “risks of an accident, incident, or miscalculation that spirals into a Nato-Russia war”, with anything from a stray missile to cyberattacks providing the spark.
This was always thought to be impossible because of the nuclear weapons’ mutual guarantee of destruction.
The US and Russia have opened up a so-called “deconfliction line” over which they can exchange military information quickly to reduce the chances of a misunderstanding.
The same method is employed in Syria, where US and Russian forces have been active on opposite sides of the country’s civil war since 2015.
But Putin has ordered Russia’s nuclear deterrent forces onto high alert and Foreign Minister Sergei Lavrov has warned that “World War Three can only be a nuclear war”.
Western analysts say such warnings should be taken as posturing to deter the United States and Europe from considering ideas such as a “no-fly zone” over Ukraine.
“These announcements are predominately addressed to a Western audience to make us fear and our societies insecure,” said Gustav Gressel, an expert on missile defence at the European Council on Foreign Relations.
“They use nuclear deterrence as a form of information operation. There’s no substance.”
