Oh, I don't suppose it occurred to you that former Secretary of State Hillary Clinton is unlikely to want to bring attention to the fact that ISIS came into being on her watch. When I did a Google search of her comments about ISIS, her statements were mostly supportive of Obama's strategy, primarily suggesting a slightly more aggressive bombing program than the current one (but supportive of the current program none-the-less).
As to JEB Bush, it is hard to imagine him coming out touting wmds found in Iraq, when his own brother did not do so as President. Even though these weapons were found while W. was being shellacked for failing to fin them, it was his decision to keep it quiet.
Of course, it doesn't help that people like you continue to believe that WMDs were the sole, or at least primary, justification given for invading Iraq, when in fact the primary justification given at the time was Saddam's refusal to abide by the agreement he made at the end of the first Gulf War.
