Facebook memory from Oct. 26, 2021:

IRGC & Islamist politicians it controls are visibly happy about protesters in France and the police roughing them up. See, we’re not the only ones!
- Sep. 2026: We have approved Ukraine’s request to manufacture Patriot missiles.
- Oct. 2026: Oil prices are up because of Zelensky’s insistence on continuing to fight. (A pronouncement made right after talking to Putin, shifting the blame from his own Iran war to Ukraine.) [2/2]
Trump on Zelensky, in the span of a 1.5 years:
- Early 2025: Zelensky is a dictator who has done a terrible job. He must agree to Russian demands because he doesn’t have the cards.
