Good job, Speaker! I'm glad you were able to reverse what was a painful situation and pull out a nice diplo win from it!
One minor note on mobilization. Going wartime does not
improve the shields on non-military buildings. If you look at the shields on the tiles building something like a temple then switch to military, you'll see the extra shields appear. Mobilizing will help finish barracks or harbor more quickly though.
I drew Mongols too, and I'll start my report tonight
