Inevitable unfortunately without the essential military kit at their disposal.
I know this isn't going to go down well but I do think the threat of an attack from Russia
" the like of which ....blah blah blah " which has been interpreted as a nuclear threat has, in some ways, been what some Western nations want. For some, Ukraine isn't worth war with Russia, conventional or otherwise. Flying a Ukrainian flag outside the local town hall is all well and good but its as much as signal of our inability to give the Ukrainians what they really need, which are tanks, aircraft etc , as it is a rather guilt ridden " we're with you in this " gesture.
If , or rather when, Russia take what we all thought at the outset of this war was their end game we then enter a very dangerous phase in as much as I cannot see any reason why Russia would stop. What are we going to do then ? Run up bigger Ukrainian flags to show our support I suppose.
