âThis administration will stand in the way of  Kim âs desire to whitewash their murderous regime with nice photo ops at the Olympics. Perhaps thatâs why they walked away from a meeting or perhaps they were never sincere about sitting down â Ayers said in the statement.
 Kim Jong Un   through  his sister   invited South Korean President Moon Jae-in to Pyongyang to begin talks âsoon.â

So we went back into the greenroom and said we have this book coming out and you should make the movie! So Mr Eastwood said to send  him  the book and gave us  his  address."

After school both  Stone and Skarlatos  opted for military careers - Stone in the US Air Force and Skarlatos in the Oregon Army National Guard. Did that military experience influence their split-second decision to try to take down El-Khazzani when he was intent on carnage?

Stone  who moments before had been dozing  charged down the train aisle as El-Khazzani levelled an assault rifle at  him .
But the weapon didn't fire  possibly because a bullet was faulty.  Stone  ended up with severe gashes to  his  neck and thumb after El-Khazzani lashed out with a box-cutter as they struggled hand-to-hand. Skarlatos and Sadler came to  Stone 's assistance.
"I wasn't really thinking about everyone else: I was just thinking about  myself  " says  Stone . "I just saw that something had to be done.

question:
Verify if the sentiment of the following document towards the entity CoinMarketCap is Positive . NEW YORK (Reuters) - Bitcoin sank on Monday after website CoinMarketCap removed prices from South Korean exchanges from its calculations of digital currency rates without any warning  resulting in a steep drop in all virtual coins they track.
CoinMarketCap shows real-time prices and market capitalizations for more than 1 300 cryptocurrencies and is widely followed by market participants. The exclusion of data from South Korean exchanges  where virtual currencies trade at a wide premium  sowed confusion and triggered a broad selloff.
Market participants said  CoinMarketCap  removed data without any explanation from three of the largest South Korean exchanges: Bithumb  Coinone  and Korbit.
 CoinMarketCap  was not immediately available to comment on  its  move.
Traders said XRP was the most severely affected by CoinMarketCap’s removal of South Korean prices because it was trading at a 50 percent premium in that country.
answer:

yes
