I get them to at least 2 in amphib research.
Thailand will join you as will Indochina. Invading them is like Germany invading Hungary, Bulgaria and Romania
Ok, I'll try to go for level 2 amphib research next game then and see whether that's sufficient.
Yup, Thailand joined me the very turn after I had posted the question. If I had known, I probably would have transported those troops (i.e. those I had on regular transports) not to Hanoi, but rather to Saigon to go to Burma from Bangkog ("three pagodas pass") instead of coming from the North (via "Burma road"). Indochina "joined" earlier by an event where I had to invest 25 MPP to occupy them.
Damn, there's *already* American subs showing up everywhere and my torpedo boats need two more turns to arrive! Also, the Philippines desaster is having consequences as they got a strategic bomber there blowing up my oilfields. I somehow have to whip up resources for staging another invasion of the Philippines soon.
