Like before, Britain made a bold statement and was ready to send troops to Ukraine
This is just as dumb a thing they said as the thing about Russian economy failing by the end of the month 3 years ago 
When we check the situation with their armies we can clearly see they already suffer from a severe shortage of men. To put simply, nobody wants to join the NATO militaries. For instance UK barely has 70k troops and all their branches of military are suffering. To the point that for example they can't even man their ships anymore!
