Capitulations will make the tension skyrocket soon. Especially kodoha Japan tends to annex all of China, tension will be at 100%
Indeed, that was the key, thanks.
I started again from 37 and this time Italy attacked Yugoslavia which was defended by France, but Mosley had done the Brit-Italian Alliance of fascists, so the british brownshirts D-dayed France and conquered it completely. This caused world tension to skyrocket and when Qing China declared independence from Japan and joined the USA alliance (what?) a 3-way world war started between:
* Fascist UK, Italy, Hungary, Bulgaria, Communist China (what?)
* Non-Aligned Miedzymorze of Germany, Poland, Baltic countries, Romania, Czech, Kodoha Japan
* Canada, USA, Qing China (what?)
So I was able to join Miedzymorze as Monarchist Netherlands due to world tension 100%....
I seriously considered giving up because the UK had 70 dockyards and 1000 convoys! While I had like 1 BB, 1 modern CL, 15 Subs 40's with Snorkels + a bunch of old useless ships.
But the AI is so bad at naval designs that I actually .... won.
I did an endless number of stackswipes using the same unchanged 1940's CL design which I created in 1939 .... and my subs massacred the british convoys.
After a long time doing this, the UK apparently go into a depression? Their fuel sank to zero despite still having 300 convoys, and they called all their ships back to port, which wasn't that many, so I am having trouble finishing the Achievement! Those coward brits are hiding from my unsinkable BB.... (seriously, the naval AI is absurdly bad if this happened), and I didn't do meta-ships, just very realistic designs, with just a little more light attack then in reality, although I do have the raiding designer and 1940's hulls)... it seems that the speed + visibility decrease from doctrine+designer makes my ships immune to enemy hits... which is extremely unrealistic.
I did avoid the british doomstack of 8 BB, 4 CV, 80 DDs, and only fought far away so they wouldn't have time to reach the battle. I'm not sure what happened to the doomstack, maybe USA sunk it.
Anyway, since the seas got boring because I refused to declare on the USA despite insistent demands from all my allies to do it, I decided instead to D-day liberate France, marched south and destroyed Spain, with the help of a bizzilion Monarchist Germany troops, which was happy to go all-in into France and left the Romanian border undefended, which I had to defend with like 6 inf against 40 enemies... but I managed to hold in that big river in Romania. It took ages to defeat Bulgaria, Hungary and Italy due to supply problems due to the excessive monarchist german troop count, but we did it, and now the USSR suddenly declared on Turkey starting another world war.
Brazil and Argentina joined Miedzymorze and started sending troops across the atlantic against USSR even while tons of american troops are storming their country.... stupid AI.
Anyway, let's see, I feel I am extremely close to the double-achievement that I craved.
I just got "Pride and Extreme Prejudice" from sinking some unless remnant UK ship which happened to be pride of the fleet. No idea what happened to the original pride of the fleet, maybe the USA sank it? I doubt the AI would spontaneously change the pride of the fleet. Good that they change it if the original was sunk at least...
Some other misc best moments:
1> Sinking the Spanish Armada with 1 BB and a few CL:
UK has no fuel and no convoy lines to import any!?
UK Doomstack can't find my sub:
