i suppose for the "non tn" nation, since it's a vote and all, it should be conducted through a poll, with garancy of anonymous voting. once every tn nation has voted, we look the result.
if it's a no or a yes.
otherwise it's easy to bring forth pressure to change one's vote for another, before the time comes.
to say, the veil voted against. since we all now know that, if somebody were to be of contrary belief, attriction would eventually be born.
and intimidation while not proven could be used by the non tn nations to declare the vote unacceptable in case of their defeat.
since neo italy has declared complete neutrality on other states sovereignity and facts, we could have neo italians take care of votes being kept anonymous. until everyone has voted, and then to proceed to the scrutiny.
this is just to say that publicly announcing one vote isn't a problem, problem is if everyone is obliged to do so.
