Input: Consider Input: “Without the reference to a June review  Russia would have been tied to the end of 2018; it wanted instead to have an escape clause ”  Petromatrix strategist Olivier Jakob  said.
“It leaves a question mark about the second half [of 2018] and about the commitment of Russian oil companies  which will be price dependent ”  he  said.
The CEO of Russia’s top private producer Lukoil told Reuters  he  would like to see the price of oil stable at current levels  trading in the $60-65 per barrel range.
The oil market is unlikely to overheat   he  added  thanks to cooperation between OPEC and its allies which would allow them to release new output into the market to rebalance it.

Input: Consider Input: Carrie Fisher  did more than reprise  her  role as General Leia Organa in the newest installment of the Star Wars franchise.
Before  her  death at age 60 last year   she  brought  her  own wit and humor with  her  into The Last Jedi â and director Rian Johnson was all about it. He included some one-liners that have that characteristic  Fisher  bite  which  she  wrote  herself .
In an interview with PEOPLE  Johnson credited  Fisher  with at least two quippy lines. The first was a line about  her  new hairstyle  she  makes to Mark Hamill's character  Luke Skywalker.
âThat was  her  â Johnson said. âThat was  a Carrie Fisher line . Of course  it  was.â
The second was a scene with actress Laura Dern  who plays Vice Admiral Holdo.  Fisher  tells her  "You go  Iâve said it enough " as the two trip over each other's words when saying the iconic line  "May the Force be with youâ at the same time.
Johnson also talked about the process of working with  Fisher . "After an hour  I would have filled up pages and pages writing down the notes and one-liners that she would pitch â he said. âAnd so we tried to work them in whenever we could.â
The zingers carry a bit more emotional gravity considering  Fisher  died almost a year ago following a heart attack. The film also plays tribute to the late actress  finishing with the note  âIn loving memory of our princess  Carrie Fisher.â

Output: Carrie Fisher wrote some of her own lines in 'Star Wars: The Last Jedi'


Input: Consider Input: Representatives of President Bashar al-Assad's government -- who have trooped through many of Geneva's fine hotels -- have never even met face-to-face with Syria's opposition.
Yes  we have been here before. But this time it feels different. Russia is calling almost all the shots  making an outcome in  Assad 's favor much closer.
Indeed  the opposition has in the past insisted  Assad  must go almost as a precondition for talks rather than an outcome of the peace process itself. And where Obama supported this position  Trump is reversing from it.
In late October  US Secretary of State Rex Tillerson said: "The only thing that changed is when this administration came into office  we took a view that it is not a prerequisite that  Assad  go before that process starts; rather  the mechanism by which  Assad  departs will likely emerge from that process."
But as we approach this latest round of talks   Assad  seemed to be leveraging Trump's implicit support  delaying  his  delegation's arrival at the talks  pushing back against opposition demands  he  needs to go early in the talks process and not be part of a transitional government.
As the US bows out   Assad  appears empowered and the UN mediator weakened. On the eve of talks  he  issued a statement demanding no preconditions from either side.
Russia and the US agree to do all they can to reach a compromise -- Russia with  Assad ; the US with the opposition.
Yet each time talks collapse because  Assad 's forces ratchet up their offensives and sieges.
The opposition  not unreasonably  says it can't negotiate while its people are being starved and killed. Mediators call for pauses in the talks that can drag out for months. The pause then only ends when  Assad  wins whatever battle  he 'd used to stall the talks.
On the eve of these talks  Eastern Ghouta -- a suburb of Damascus -- is in the headlines. It is the latest pocket of opposition  Assad  is trying to extinguish. International observers will be watching carefully  albeit with no clout to change the dynamic  should  he  use the cover of these talks to accelerate attacks here.
Each time has  Assad  crashed the talks previously  Russia -- rather than convince  him  to stop -- has helped provide cover for  him .
That was Obama's understanding with Putin. The US believed Russia would do as it said it would -- namely  telling  Assad  to stop fighting -- and negotiate in good faith. It never happened.
When finally Russia did vote for UN Security Council Resolution 2254   calling for a political  not military solution and setting a time frame and process for  Assad  to end the war and transition from power  it seemed impossible the Russians could weasel out of their obligations again. Yet they did.
For any democratic leader  victory at the cost Syria has paid -- hundreds of thousands dead  more than half the population displaced  and close to 5 million refugees forced to flee the country -- would be pyrrhic in the extreme. But not for  Assad  and  his  ally Vladimir Putin.
How different things are now. As parties get ready to arrive in Geneva  Putin recently held a meeting with all the key powers in the region and beyond  which was notable for  Assad 's presence outside Syria for the first time in seven years.
That a man as paranoid as  Assad  could be lured from his safe Damascus lair is an indication of the influence Putin holds over him.
