Perhaps it's the pessimist in me but despite the celebrations in Yemen Idon't think it's the end of the trouble just yet. I hope I am wrong but after initial jubilation at the relatively quick overthrow of the regimes in Tunisia and Egypt the "Arab Spring" has stalled somewhat. Bahrain has cracked down on protesters whilst Formula 1 prepare to welcome them back into the fold and initial speculation that it would be a matter of days, or a couple of weeks at most, before Gaddafi was overthrown the fighting in Libya continues.
   Whilst it is certainly difficult for Saleh to return to Yemen after he receives treatment his regime is still in power with his vice president assuming control. Much therefore depends on whether the protesters are happy enough to see the back of someone who ruled them for over 30 years or as is more likely wish to continue to press on and seek reforms. Hadi may have a bit of time to assess his position whilst Saleh recovers as he is effectively in a caretaker role and he will have to decide which way to handle things should Saleh remain in Saudi Arabia: Continue with the damaged regime and risk going the way of Saleh or bow to the protesters demands and not try to hang onto what he has not had and spare more bloodshed.
