Syria may be a few “weeks” only a “great transition” between the political regime in Damascus and the opposition, held in Paris on Tuesday US Secretary of State John Kerry, in the wake of international compromise concluded in Vienna.

We are not talking about months, we’re talking weeks, hopefully ” Mr. Kerry told a few reporters traveling with him in the French capital, four days after the attacks in Paris.

“Now all we need is the beginning of a political process and that the cease-fire is established. This is a huge step,” said Kerry, referring to the text of Vienna which provides a meeting between the Syrian regime of President Bashar al-Assad and members of the Syrian opposition by 1 January 2016.

A possible cease-fire, elections and a new constitution are also provided by the Vienna compromise signed on Saturday by a score of powers, including Russia, the US, Iran, Arab and European countries.

Kerry welcomed that “Iran and Russia are at the table” negotiations, “it’s only for four and a half years” of war in Syria that killed at least 250,000 dead and millions refugees and displaced persons.┬áHe also advocated that Saudi Arabia, which supports Syrian opposition groups, meet very soon under the auspices of the UN, for they can then meet with representatives of the Syrian government.

The meeting in Vienna, which boosted hopes of a political settlement in Syria, however, stumbled again on the fate of President Assad. Europeans, Arabs and Americans want him to leave power. The Russians and the Iranians continue to support their ally.
