If South Vietnam is allowed to be in, they vote:
aye on allowing nations not in SouthEast Asia into SEATO (Japan is not in SE Asia, and in SEATO)
aye on letting the USSR in
defers on voting on letting Spain in, unless they become a democracy
aye on the Nuclear Research Center project
Thailand is astonished that it is not being allowed to annex the remaining part of Burma that are in anarchy, seeing that all other SEATO nations have annexed parts of land, Australia most of Indonesia, Japan part of Yemen, Malaysia Brunei, and parts of Borneo, and New Zealand East Timor, and various other islands. They aer shocked at the outrage over such a bit of land, and they demand an explanation as to why they are not permitted to take land, but other nations are. Oh, and the NKE have taken over much of Burma.
Thailand echoes Indians complaints about this being a very hypocritical organiztion, and are considering pulling out of this organization, and not sending troops to beat back the Commies in South Vietnam.
