I've seen a lot of puff pieces about Hillary's excuses and justifications for her IWR vote.

The 5 Worst Excuses for Hillary Clinton’s Vote To Invade Iraq
Clinton supporters want Democratic voters to forgive their candidate’s support for the most disastrous foreign policy decision in decades. They shouldn’t.

1. “Hillary Clinton’s vote wasn’t for war, but simply to pressure Saddam Hussein to allow UN weapons inspectors back into Iraq.”
At the time of vote, Saddam Hussein had already agreed in principle to a return of the weapons inspectors. His government was negotiating with the United Nations Monitoring and Verification Commission on the details, which were formally institutionalized a few weeks later. (Indeed, it would have been resolved earlier had the United States not repeatedly postponed a UN Security Council resolution in the hopes of inserting language that would have allowed Washington to unilaterally interpret the level of compliance.)

Furthermore, if then-Senator Clinton’s desire was simply to push Saddam into complying with the inspection process, she wouldn’t have voted against the substitute Levin amendment, which would have also granted President Bush authority to use force, but only if Iraq defied subsequent UN demands regarding the inspections process. Instead, Clinton voted for a Republican-sponsored resolution to give Bush the authority to invade Iraq at the time and circumstances of his own choosing.

In fact, unfettered large-scale weapons inspections had been going on in Iraq for nearly four months at the time the Bush administration launched the March 2003 invasion. Despite the UN weapons inspectors having not found any evidence of WMDs or active WMD programs after months of searching, Clinton made clear that the United States should invade Iraq anyway. Indeed, she asserted that even though Saddam was in full compliance with the UN Security Council, he nevertheless needed to resign as president, leave the country, and allow U.S. troops to occupy the country. “The president gave Saddam Hussein one last chance to avoid war,” Clinton said in a statement, “and the world hopes that Saddam Hussein will finally hear this ultimatum, understand the severity of those words, and act accordingly.”

When Saddam refused to resign and the Bush administration launched the invasion, Clinton went on record calling for “unequivocal support” for Bush’s “firm leadership and decisive action” as “part of the ongoing Global War on Terrorism.” She insisted that Iraq was somehow still “in material breach of the relevant United Nations resolutions” and, despite the fact that weapons inspectors had produced evidence to the contrary, claimed the invasion was necessary to “neutralize Iraq’s weapons of mass destruction.”
