Thank you, IDS class 2025-26. You’ve been great! Good luck to our Canadian investment vehicle, AgriGarima, in navigating the choppy regulatory waters of Utopia, and good luck to all of you in the exam. Does this make sense? I hope it does!

I’ve been a low-key fan of this pod since it started - I particularly enjoy the “what everyone gets wrong about…” sub-series. Deliciously irreverent and appropriately highbrow. But for this one I have to thank the co-hosts for the shout-out. Perhaps I need to write about 2803.
New episode of #CalledToTheBar is out! We break down UNSC Resolution 2803 and the bizarre reality of Donald J. Trump’s Gaza “peace plan” becoming international law. Self-determination? A “Board of Peace” chaired by Trump and Blair? We have questions. So many questions.
