What I find worrying is the standard tactic seems to be to do negotiations, let the other side assume there is hope for a other solution - and then attack hard all of a sudden. Already the second time. It might be effective short term, but it erodes what is left of trust negotiating with the US.

It may not work but it's not a bad objective. My mum in the UK is a Bahai and a lot of those are refugees from Iran because they say be nice and tolerant and the Iranian government imprisons or kills them for so doing. Blasphemy etc. The are not a good lot.
