Western officials say Russia cannot launch a major offensive as Ukraine’s military casualties reach 200,000.

Ukrainian and Russian troops have lost about 200,000 troops to date, according to Western officials.

Of the 100,000 killed or wounded on both sides, more Russian servicemen are reported to have died.

However, the estimate does not take into account the number of Ukrainian civilians killed or wounded, which has been estimated at around 30,000 since the start of the war on February 24 last year.

Western officials remain skeptical about Russia’s ability to launch a widely anticipated offensive by spring, amid continued problems with the military supply chain and a shortage and poor motivation of forces.

“We are seeing Russian security forces fragmented and overwhelmed by the Ukrainian operation,” Western officials said.

The West believes that Vladimir Putin’s mobilization of some 300,000 civilians for war is unlikely to help the Russian president succeed.

“Hundreds of thousands of reservists were unlikely to be formed into dense formations capable of conducting large offensive operations,” the official added.

Ukraine also said it had received promises to supply more than 300 tanks from countries such as the UK, US, Germany, Poland, Estonia and Spain.

Ukrainian Ambassador to France Vadim Omelchenko said: “To date, many countries have officially confirmed their agreement to supply Ukraine with 321 heavy tanks.”

Mr. Omelchenko did not specify which countries would supply the tanks or sketch models, but his announcement came after the US pledged to supply 31 M1 Abrams tanks and Germany agreed to send 14 Leopard 2 A6 tanks.

The UK is sending 14 Challenger 2 tanks, while other European countries are sending both German-made Leopards and Russian-made T72s.

However, the tanks are not expected to arrive in Ukraine in large numbers in the coming weeks.

Despite the surge in Ukrainian technology, the West does not expect the war to end this year.

“If you add up all the pros and cons, you end up in some sort of harrowing conflict that currently looks like it will last until 2023 unless something else changes significantly,” the officials said.

“This does not mean that there will be no exchange of territories, but will the exchange of territories lead to a change in the status of the conflict? We don’t see it at the moment.”

There is also information that Putin plans to remobilize his population in order to increase the number of troops.

These include raising the maximum age for recruits from 27 to 30, increasing the recruit pool and possibly college students.

“The question is how Russia mobilizes,” Western officials said. “Is this a partial behind-the-scenes mobilization? Low degree of mobilization? Is it a full mobilization that can be politically difficult? I think the Russian system doesn’t know exactly how to deal with it yet, but we’ll be watching closely.”
