Iraq war is not a suitable comparison. That event was a decisive US victory that resulted from thorough planning, extensive international support and collaboration, and total commitment from all parties.
Trump's wars are none of the above. Mobilizing a couple thousand troops here and there for a war that can be orders of magnitude more intensive than Iraq War V2 and without any semblance of support is a clear sign of starting a war while signaling their own impending defeat.
Let's not fool ourselves: the only parties benefiting from this nonsense is Russia and China.
