Indeed, I would say that it would be difficult to pin the blame on one sole party. You have obvious candidates like the Mythic Dawn, but as Br3admax mentioned, the Nerevarine freeing the Heart of Lorkhan also weakened the Liminal Barrier suffieciently for the unlight Dragonfires to also allow the Oblivion Crisis.

Why blame the Dominion, though? They were not even around at the time. The Blades, of course, do hold some resposibility, but I do think that people are a tad harsh towards them, it is not as if they did not try to protect the Emperor.
