Go for the source... ARF calls only for Underling Resignation

The ARF is just finishing up a big meeting in NKR, and one of the things to come out of it is their demand for the resignation of... Nalbandyan. Because they don't like what's coming down the line for Kharabakh, and Nalbandyan is foreign minister, and Sargsyan's policy is failing... This doesn't make sense on multiple levels (RFE article).

“If anyone is to change the foreign minister, it must be the president. If he does so, it will mean he is changing his policy,” said Manoyan

So, somehow, if you don't like Sargsyan's policy, then you get rid of the guy implementing it ( As Unzipped has already pointed out, no one really believes that Nalbandyan is making policy.) ... And bringing in a new guy somehow means a new policy. But Sargsyan will still be there. Apparently the outward signs of new policy are not new policy statements or decisions or actions or outcomes, but a new minister. Which means either the ARF believes that the old minister represents other powers who are forcing Sargsyan to do things he doesn't really want to do, or a new minister would be able to change Sargsyan's mind, or would represent a force that would change his mind. Or maybe they just want their own guy in there.

And why not just ask for the resignation of Sargsyan himself?

“Our problem is that if a leadership change implies the coming of several figures of the [Armenian National] Congress to power, then we have no guarantee that these forces will not conduct an even more conciliatory policy than the current ones,”

If they were willing to look closely, without blinders, at the past and the present, maybe things would be clearer. Maybe they have, and they really, truly don't like the policies of the 1990's. But its hard for me to see how having a president supported by the people, who is able to focus on the problem at hand for what it is, could be worse than having the current president, not supported by the people, pressured by international powers due to questions of legitimacy and human rights, struggling to keep his position and willing to make concessions to keep it, with a track record of making false starts to look good.

Maybe they don't think its Sargsyan's policy, but someone else's, so getting rid of Sargsyan wouldn't do anything. Maybe they just never truly cut their ties with the authorities, and don't want to go that far, maybe that would really start making them look like Opposition.
