.... and this is a problem because of its damage to "US Credibility"

The failure of the makers of the Iraq War to consider broader follow-on consequences includes not only insurgency and retaliation but also effects of the war on the global standing of the United States and its ability to influence other states on other issues. Relevant to this failure is Russia’s ongoing war in Ukraine and the U.S. effort to sustain an international coalition in opposition. In defending his operation against U.S. criticism, Russian President Vladimir Putin has been quick to mention the U.S. invasion of Iraq and to accuse Washington of hypocrisy. To American ears, this rhetorical line is annoying whataboutism, but Putin has a point.
