I am in two minds about this one. I do think this is a retrograde decision, but I can also see (steelman?) a perspective from the DoW that they were entitled to make assumptions about the inputs they use for planning and the inability to follow through on those assumptions means they can't now "supply" the kinds of intelligence they sought.
King for a day I wouldn't have done this, but the current king (of the hill?) has, and the court aligns to his intent more often than not these days.
