I agree completely about Iraq. The Bush II administration sought to undermine the rules-based international order, particularly its leading authority the UN Security Council. That dovetailed with their desire to invade Iraq.

The blow was significant - the US fabricated and misinterpreted evidence to justify the invasion, not only conducting an effectively illegal international war and violating that most fundamental of international laws, but also undermining the integrity of the international order's leader, the US itself. The rest of the West was so happy when Obama took over, he got the Nobel Peace Prize before he did anything - I think just for supporting the liberal order.

But like all recent Democratic leaders, he didn't fight much for it or for its values. Then Biden particularly was egregious, abandoning the cause of freedom (in Afghanistan, west Africa, India, China, etc.). His support for Ukraine and Taiwan appeared, to me, strictly geopolitical. In fact, I remember hearing that US officials had a policy to argue not for Ukraine's freedom and democracy, but for its sovereignty - and they seemed to observe that policy.

Without values, you have no direction, no force, no way to lead or organize. Biden's enemies have clear values - nationalism, ethnic nationalism, power (as value in itself). What were Biden's? What are the Democrats'? They've shut down the government over no value, only healthcare funding.
