Well that's fair enough, except it depends what you mean by 'far away'. This forum is socially and linguistically a lot closer to London than it is to Kabul. Ergo, it's not very shocking that this event gets more attention here. It's just human nature.
And, not coincidentally, for some of us here this attack occurred geographically very close by (i.e. a short walk away - another weekend I might have been there).
Be nice if the OP would explain what point they were trying to make - why they thought there was any logic in juxtaposing two different tragedies.
If the point was that our various humanitarian liberal interventions in the region have only made things worse, and that therefore there's some sort of connection between them, then I don't entirely disagree. It's one reason why I couldn't feel much enthusiasm for 'uberhawk' Hilary, even in the face of Trumpaggedon.
