The Guardian has been giving pretty decent coverage to the Yemen conflict (and the US/UK/Saudi relation it) overall, actually. Well above the level most people in the U.S. would have a stomach for, were they to actually pay attention to this rather horrid and depraved state of affairs being conducted on the global stage, in their names.
At the same time, there are only so many column inches available, and there's only so much effort (and so many lines) one can devote to the regurgitating the broader context (that's generally covered in other articles they run).
