Wow, reading this thread is like watching Faux noise.
Let's not let details spoil a broad brush smear.
First the released detainees are SUNNI men while the rebels are SHIA. Enemies not partners... :doh
Next two of the released detainees are dead due to drone strikes. Thank you Obama.
Third the issue is still in flux and there is little 'hope' the SUNNI faction will be in power.
Fourth, while it is disturbing to the 'crown' prince for Yemen to be openly an ally of Iran the fact is until recently the Sunni majority was suppressed in Yemen. While many don't like the rebels they are Shia and not likely to side with an ancient enemy, the Sunnis.
So using facts this is annoying to Saudi interests and until now the Saudis gave little attention to Yemen internal politics as long as the Saudi interests were upheld.
Sort of the way the Good ol' USofA handles much of the world...
