Personally, I’d let Putin have Germany, rather than see another Brit, American, Canadian or other nationality soldier die on their behalf... because that’s where this will end.
rather a blinkered view MGD - where would Putin look next if Germany rolled over? France next to ensure warm water ports and then probably UK because our military hasn't the capability to defend ourselves alone.
So then you have to wait for the USA to join in or have a European Army to defend Europe........
