Yeah this always seems to be the main concern I see raised on discussions about Western v Russian geopolitics. I've never heard of it actually being mentioned by any Western military or government official but you don't exactly expect them to talk frankly about geopolitics anway.
Probably this in part, but also because his popularity has been tanking since covid and the recent string of covid related scandals he's embroiled in, so I think it's largely an attempt to look strong on the issue and regain some public support. If he's replaced by another conservative before we get to our next gen election (scheduled for 2025) then I would imagine we'll continue this same policy regarding Ukraine since there's a lot of public support for Ukraine here and conservative voters tend to favour military support (I think).
Alright Mr Dillon
