PROBLEM: Verify if the sentiment of the following document towards the entity Nikki Haley is Positive . But  U.S. Ambassador to the United Nations Nikki Haley  expressed confidence the transfers could be blamed on Tehran.
“These are Iranian made  these are Iranian sent  and these were Iranian given ”  Haley  told a news conference at a military hangar at Joint Base Anacostia-Bolling  just outside Washington.
The unprecedented presentation - which  Haley  said involved intelligence that had to be declassified - is part of President Donald Trump’s new Iran policy  which promises a harder line toward Tehran. That would appear to include a new diplomatic initiative.
“You will see us build a coalition to really push back against Iran and what they’re doing ”  Haley  said  standing in front of what  she  said were the remnants of the Nov. 4 missile.

According to  Brown   Smith’s girlfriend Iris Love submitted a story about her trip up the Nile to Vanity Fair in 1985  shortly after  Brown  had started her new job.
“Trouble is  picture’s great  copy not  ” Brown  recalled. According to  Brown   31 at the time  she decided to run the piece anyway  but only after a heavy edit that she knew would not go over well with Smith. As expected  Smith “got on the horn to give me the full Texan bawl-out.”
