I was just going back to Secret Invasion and seeing how the POTUS and Thor put the blame squarely on Starks shoulders for the Skrulls fiasco, and wondering are they right? There has been argument that because Stark put all his eggs in one basket that's why the Skrulls were so easily able to destroy the Earths infrastructure. But really, the Skrulls were going to figure a way to do that even is SHIELD was in charge, so I don't see it as a deal breaker for Stark.
And then there is the bigger question of if Stark didn't take up the case of the Pro-registration side in the Civil War, that the whole series of status quo changes would never have happened either, resulting in the current situation of Avengers vs X-Men. But what if AVX happened before CW? Would it have gone any better than it did after the Heroes lost and had to attack the X-Men as government goons rather than free vigilantes? I don't see it. I think Stark did the best he could do under the circumstances and that the way things panned out with the Initiative, WWH, SI, Dark Reign, Siege, HA, FI, and AVX are not the fault of Tony Stark, and that he's been hung out to dry.
Does anybody feel Stark has a case to answer? I saw Stark standing on his lonesome after SI, a little despondent and alone, and thinking, why is everyone laying this all on Tony? To this day, it's Stark who has been marginalized as the villain of this period in Marvel history.
