I normally think that when a thing is referred to by the initial letters of its proper name there is no need to add an S to pluralise it. The plural S is hidden behind the initial capital letter. So we have, for example, OS. You would not ask how many different OSes are there? You would ask how many different O(perating) S(ystems) are there. The plural s is hidden. There are exceptions of course but these prove the rule for the combination of the initial letters has become a noun in itself which does not describe the same thing as the string of words describes, so though we refer to LASER, if we have two sources we shall speak of having two lasers.
I should also like to make a further exception in response to a suggestion by a Western oligarch that one country become an special administrative region of another country. I shall refer later to this as the Type B proposal. That other country is well known for its SARS which were first identified there about twenty years ago. Much effort is put into the elimination of these SARS for they are quite dangerous things. The effects that they have on the people of that country are quite severe and if left uncontrolled would have serious adverse social and economic consequences, so the (dis)benefits of these SARS must, so we are led to believe, be curtailed at all costs.
The truth of these remarks would of course be clearly seen if the doctrine behind this suggestion were pressed to its logical conclusion, and it was proposed that the other country should become a special administrative region of the one. The objective of the underlying doctrine would be equally achieved. I shall refer to this as the Type A proposal.
Both proposals are the logical outcome of the foundational doctrine held by the other country, so why would not a Type A solution be acceptable to it? Is it a fear that it, as a SAR, would go the way of all other SARS?
