God created war so that Americans would learn geography. Like Trump's obsession with Greenland because he does not understand the Mercator projection...
If you've been paying attention you'd understand that (1) the US military brass has been almost entirely replaced by MAGA stooges who think the rapture is real and (2) Trump and co 100% thought they could Maduro-esque behead the IRGC and this would be over in a week. The military officials who (correctly) dare not attack Iran aren't in any positions of power any longer.
