Japan
Fellow leaders,

What would be the quickest way to annex USA as Facist or NonAligned Japan?

I can island hop to secure naval routes

I tried Hawaii to California, can work but unless pacific islands are cleared , by the time I can set up naval invasion support on the west coast my convoys are destroyed.

Alaska to Northwest USA?

I am looking to simply land my armies , and take USA out in 1936,

Open console commands
type Annex USA
Completed Jan 1st 1936 12:01 pm

On a serious note, convoys build them or get your relations up and buy them from other countries before declaring. Honestly never tried defeating the US in 36 but that would be my thoughts if your issue is convoys.

Haha. Console commands are great to toy around with.

Yeah, if I island hop , I am able to secure all naval lanes roughly by end of 37 due to island hopping taking some time and USA is annexed in 1938. Convoys are eaten like candy by the USA if I don't eliminate them from the pacific.

I am just seeing if there is a quick blitz strike right off the bat.

Going for the mexico and then europe achievement and just want a quick quick fix. But will dig down and do it the old way. Shouldve done that achievement when I did all the other ones for Japan.

Bit counterintuitive but don't go for America first but rather look at Europe: Sunrise invasion requires you to annex Mexico before taking a state in Europe but there's no rule against going to war against a European nation and taking their states elsewhere.

Get military access from Germany, justify on the Netherlands and naval invade from the German coast.
Annex the Carribean isle (Curacao, IIRC), puppet the rest.
Justify on any American country but Mexico and Canada (otherwise they'll pour troops in the USA to augment their frontlines, which is something that doesn't happen if you use Panama as Casus Belli); plan a naval invasion into Florida.
Invade the USA from Florida and pour in as many troops as you can; you should be able to do this by early 1938 and with negligible world tension so the US Army will be small and weak.
Before capitulating the USA justify on Mexico so it goes fast.
Declare on Mexico, cause them a couple of losses and cap the USA.
Seize the US Navy and use it to invade Europe from your Netherland puppet / simply annex it.

One time i tried a trick that i saw in youtube. I built a few long range cruise submarine and declared war on a facist mid american country. I escorted my naval invasion with those submarines and landed my army on usa mainland but i was defeated.

I think they patched that military access from Germany aspect , as that would make sense to declare on one of Britains subjects and simply capitulate Allies , taking Canada in 1936 and quickly overrunning the USA and having the UK fleet as well.

Your approach is similar to one I can do , but in that case I would simply outright declare on Mexico to get USA involved and island hop the Pacific , and by 1938 USA will be annexed.

I gotta see if the military access for naval invade would work from Germany though. Thanks for reminding me about that haha.

If you land and take a port and have enough convoys , by late 1936 , you can have around 120 divisions , lacking equipment , but there goal is to overrun and encircle in the mainland. My issue last playthrough was no convoys and my 10 divisions that took Los Angeles had no supply coming and couldn't leave as my convoys were picked off in the Pacific.
I overlooked that aspect and had a oh moment.

They tried to intercept convoys around my mainland so i used my naval bombers (imo best option to hunt submarines) to hunt them down. USA lost of most its submarines this way and couldn't effectively disrupt my supply convoys. They defeated me because i didn't know much about warfare (and still don't know much) and wanted a big start in game as japan to compensate for that.

join axis, naval invade or paradrop UK, use carribean UK or french assets to launch naval invasion for east coast, where all the high VP are.

or take out mexico, use southern border, but thats more grindy.

regardless which route you take, build agency first, get 3 spies, keep boosting ideology, anything but democracy. if USA gets under %95 democracy then it cant take the game changer focuses, cant ramp up its economy, cant change mobilization or recruitment laws.
USA will end up with best case scenario max 400k manpower, roughly 45divs which poorly equipped. some of them even half strength. if there s no allies he can run to then you can capitulate it in few months, thats why i suggested taking out UK and lackeys first.

I did it the old fashioned way. Historical AI , built up until ww2 , had 300 infantry divisions 12infantry engineer support , started justifying to get same time as Allies against Germany war start, naval invaded UK , took them out and took Canada and navies and some Pacific resource rich areas, took out USA from Canada , took out Mexico, used German France to naval invade Portugal and get achievement.

I took your advice about the agency, I have not played USA in so long it hadn't crossed my mind that the focus requirements are so stingy for USA. It worked even though my spies kept getting caught and executed. Great advice!

yes i know, im sry, after a while USA gets paranoid and works on counter intelligence and spies keep getting caught but nothin to worry, because AI cant get their democratic ideology back. i just kept boosting for the lols after %95, until its %40 non-aligned. reason is, also to lower their stability.

Why sorry? it worked great , got USA to 18% Facist but stopped because I didnt know if a civil war would trigger and I did not want that haha.

im sry because sometimes there re very good spies rolled for us with lotta useful traits and they either killed or they get captured, and when they captured,if you re a minor,sometimes you cant afford any civ or equipment to release them because we re busy building our army with defecit also. but in japan's case its not a problem i believe.

when i lose such spies, i feel like i lost a child lol.

They served their purpose honorably haha. To be honest I rarely had used the intelligence system in hoi4.
