Myanmar is a definite possibility, as is Sudan.

[CaptIsaacDavis]

Burma -- no way (offered as a former FP specialist on the country)
Sudan -- no how (no money).

Syria
Nigeria (military rumored)
Brazil (new communist leader came into power promising to build the bomb)

South Africa (ANC radicals could change Mandela's policy as he is sick, and certainly when he dies)?
Former Soviet Central Asian country?
