General Discussion

It assumes Trump is just clueless, ignorant, or whatever other term you want to use to describe someone who's so stupid he couldn't pour piss out of a boot with the instructions on the heel.

No sir. Trump's handlers knew EXACTLY what would happen when he did this: the Iranians would close the mouth of the Persian Gulf, and the only way Trump could "rescue" Americans from having unleaded regular cost more than avgas is to allow Russian oil to be sold in the United States.

This is what I think happened.

1. Russia is allies with Iran, but Russian dictator Vladimir Putin finally had enough of Iranian dictator Ali Khamenei's shit.
2. Putin would send his own people down there to throw Khamenei out of a 40th-floor window, but the Russian 13th "Alexander Bortnikov" Guards Defenestration Brigade is currently stuck in Ukraine.
3. Putin's solution is to give Donald Trump Khamenei's location and order him to kill Khamenei. Trump does as directed.
4. Iran issues a two-pronged response. First, they install a new dictator Trump and Putin will hate even worse than the one they murdered. Then they close the Strait of Hormuz, which has two effects: it starves the other Gulf States because they can neither import food nor export oil, and it sends the price of gasoline everywhere else through the roof.
5. Trump lifts sanctions against Russian oil, which does two things for him: it makes his controller in Moscow very happy, and it allows him to erase something else President Biden did without looking like the evil fuck he is.
