There is in no way I would stand up for the UK given its relationship with the money Putins chumocracy offers some. Knowing full well some of my countrymen have enriched and continue to enrich themselves while sending others of right, you must be joking...
If the UK was directly threatened with invasion, you wouldn't fight? Most people in this country can't even comprehend the position their citizens are in.
It's not about "fighting for your country", it's about fighting for what's right. All of this navel gazing in this thread but we don't really give a toss as it doesn't directly affect us. Maybe if it did we'd be pushing our government to do more than impose meaningless sanctions while leaving Ukraine to its fate.
To the first point, I think it's a combination of both. They'll be fighting for Ukraine, which ultimately is what is right in this case.
To the second point, I agree and disagree. There'll be many for who it's the current event, but their outrage is tokenist in the sense of it'll be forgotten soon.
For others, there's a real drive to undertake meaningful actions to protect Ukraine and wider Europe. But, there's a realism of what can be done effectively.
