'British mothers have to accept that their sons will have to die for Nato'

‘But the real question is,who is going to tell the voters that the threat of the war is real?’

Kuleba’s warnings come from a wealth of experience. Before the beginning of the war,no one in Ukraine – and the rest of Europe – did actually believe that Russia would invade and proceed to massacre tens of thousands of civilians and soldiers.

He also made the mistake of thinking that after a certain number of Russian losses in Ukraine – ‘like 10,000 and 20,000 soldiers’ – Putin would eventually withdraw.

It is estimated that one million Russian soldiers have been killed and wounded since the conflict began in Feburary 2022.

Kuleba said: ‘Telling the truth to people about the prospect of war in Europe is what requires more attention than anything else…

‘People in Britain or any other country can listen to what I’m saying or they can decide that I am a warmongering Ukrainian who is trying to pull them into my war.

‘I am perfectly fine with any choice they make. What I can say,what I can urge them,is not to repeat our mistakes.

‘The biggest mistake Ukraine made was that we did not believe that this can happen to us on this scale. We,in Ukraine,also believed that it is not going to happen to us because Putin would never dare to do it.

‘So this is the mistake that people are making. I look around in Europe and I just see the same pattern happening. The same pattern of behaviour.

‘Do you think that if Ukraine was able to attack airfields in Russia,1,000 miles away from Ukraine,Russia is not able to attack any piece of infrastructure in any European country? That would be a very,very big mistake to think so.’
