question:
(CNN) -- During the last four months, the people of Ukraine have been fighting for their freedom, independence and European path in a war started by Russia-backed terrorists and their accomplices. Ukrainian military forces suffer heavy losses in battles against terrorists equipped with the newest Russian weaponry. We've seen reports of the pro-Russian thugs shooting women and children, cynically calling it a "protection of the Russian-speaking population." The price we are paying to bring peace back to the regions of Donetsk and Luhansk in eastern Ukraine is too high. Ukrainian President Petro Poroshenko has proposed the decentralization of power as part of his peace plan. It means more freedom, more economic autonomy and more opportunities to use languages spoken in a particular community for every region.Pavlo Klimkin: With downing of MH17, price of peace in eastern Ukraine already too highKlimkin: Ukrainians know bitterness of loss, share grief with families of the deceasedHe says the guilty must be promptly punished

question:
(CNN) -- People don't generally care what politicians read. But Rep. Paul Ryan is different. His fascination with the Russian-born novelist Ayn Rand could spell trouble for the GOP's new vice-presidential candidate. It could put him at odds with the Christian right and the Roman Catholic Church. It all depends how much you believe that he is in the thrall of Ayn Rand. Rand (1905-1982) is controversial because of the extremism of her views. In researching my recent book, I found that Rand's influence on the Republican Party, which dates back as far as her endorsement of Wendell Willkie in 1940, has been sharply growing, largely due to her vise-like hold on the imagination of the tea party and people like Ryan.Ayn Rand was a Russian-born novelist whose work celebrated selfishness, says Gary WeissIn April, Paul Ryan called reports of his adherence to Rand's views an "urban legend"But in 2005 Ryan said she was "the reason I got involved in public service," says WeissWeiss: That could put Ryan at odds with the Christian right and the Roman Catholic Church

question:
(CNN)Some members of the U.S. Congress may be resisting proposed new sanctions on Iran, but their opposition doesn't seem likely to stop Congress passing legislation on Tehran's nuclear program by the end of March. As one of the negotiators who sat across the table from the Iranians for the past 15 months, though, I can assure you that legislation at this juncture risks undermining a deal that is clearly in the interest of all parties. Fortunately, there now seems to be broad consensus that introducing more sanctions with immediate effect would simply play into the hands of Iranian hard-liners. With that in mind, ideas for moving legislation have turned to focus on two concepts: establishing a "trigger" for new sanctions, linked either to an arbitrary future date or a collapse in the talks, and defining what would constitute a good deal and requiring an "up or down" vote on it.Congress has been discussing whether to impose more sanctions on IranRichard Nephew: Movement of such legislation still risks sparking escalatory cycle 
 Questions:If the point is to create red lines for the Iranian negotiators, then _ will have the opposite of its desired effect: defining a "good deal" in detail forces Iranian negotiators to cross our red lines to maintain their revolutionary credentials and sell a deal at home. (A) CNN (B) U.S. Congress (C) Iran (D) Tehran (E) Iranians (F) Iranian (G) Richard Nephew
