Jeb!'s problem with Iraq goes beyond mere loyalty to his brother. His foreign policy advising team is dominated by veterans of his brother's administration. The people who brought about the collapse of that country have an enormous incentive to portray anything that happened there as someone else's fault.
Jeb! is simply not going to get objective analysis about Iraq. Maybe he is really unaware that the "premature withdrawal" he slammed happened to be the withdrawal schedule that his brother agreed to in a bilateral agreement with Iraq. Lots of people don't seem to know about that and Jeb!'s advisors have plenty of reasons to sweep it under the rug to hang some of the blame for the current mess on the Obama administration or his former Secretary of State.
