I wonder what's going on in Afghanistan right now, for instance, and is it worse than an illicit Chritmas party or having someone else pay for your wallpaper? Given the amount of coverage by the BBC, obviously not.
News is an entertainment product - the main thing that determines what dominates the agenda is what people find interesting and gets eyeballs, not some abstract measure of "worthiness".
And in addition, it is perfectly OK for the national news of a country to focus on issues of importance to that country (such as matters that relate to the honesty and integrity of the prime minister) rather than Indian national health policies or whatever the worthies think is of most importance.
Not that it is even worthies making this comparison of course - more like pathetic attempts to distract.
It happened on Biden's watch, so people will remember Biden as owning it.
But yes, Trump was the one who decided to pull the plug.
That said, Biden didn't really have to go along with whatever Trump had started, so it was his choice too.
I expect Trumpers to claim credit for the withdrawal, and to simultaneously blame Biden for the defeat, often in the same paragraph. (It's not cognitive dissonance if you know it's all bullshit.) And Democrats will play with a variety of unconvincing narratives, including "Trump tied my hands".
But ultimately, most people are going to view the withdrawal as having been more-or-less necessary, and will recognize the blame game for what it is.
