Can president Saleh go back?

Yemeni president Ali Abdullah Saleh left Sana'a for medical treatment in Saudi Arabia late Saturday. Activists were singing and dancing in the streets celebrating their great victory.

"Leave" and "departure" where the words most used in protests in Yemen (as well as in Egypt, Syria, Libya and Tunisia)

This is why the fact that he is out of the country made them rejoice.

Some people are still worried because neither he officially resigned nor did any from the government, especially his deputy who took charge after Saleh left to Riyadh, had made any announcements that Saleh is not in power anymore. On the contrary, they stressed the opposite.

However, is it really going to be hard for Saleh to go back, because it will make things worse in the country. The question would be if the Saudis will let him go back, or they will succeed in convincing him to sign the transfer deal, he refused three times before.
