Question: Rex Tillerson could be on  his  way to serving one of the shortest tenures of any Secretary of State in U.S. history.
âThere are no personnel announcements at this time â White House spokesman Sarah Huckabee Sanders said in a statement. â Secretary Tillerson  continues to lead the State Department and the entire cabinet is focused on completing this incredibly successful first year of President Trumpâs administration.â
âHeâs here.  Rex  is here â he said.
If  Tillerson  leaves in the next few months   he  would likely be viewed as one of the most underperforming secretaries of State in U.S. history with one of the shortest tenures to boot  say experts on American foreign policy.
âIt will ratify what is emerging as almost a consensus view that  Rex Tillerson  was the worst Secretary of State in modern time â said Paul Musgrave  a political science professor at the University of Massachusetts-Amherst who studies American foreign policy. âI actually think there is a good case to be made  ever.â
If  Tillerson  leaves in the next few weeks   he  will have served for roughly a year  inordinately short for a first-term Secretary of State in the modern era. The last three first-term secretaries of State â Warren Christopher  Colin Powell and Hillary Clinton â all remained in their posts for the entire term.
Aside from his short time in office   Tillerson  has little to show as accomplishments.

Answer: Rex Tillerson


Question: Leading Tory Brexit supporters have urged the prime minister to take advantage German Chancellor Angela Merkel ’ s weakness and failure to form a government . Theresa May has reportedly agreed with her cabinet to roughly double the offered Brexit ‘ divorce bill  ’ but Iain Duncan Smith   the former Conservative Party leader   urged her to “ sit tight ”  The Times reports . advertisement Jacob Rees - Mogg   Tory MP for North East Somerset   said that it would be “ foolish ” to hike the offer at a time when Mrs .  Merkel  needed to reassure German voters and businesses they will still be able to trade with the UK .  He  told the paper : “ Approving a higher divorce bill at this stage would be foolish … As for Germany   its domestic political concerns make it less likely that it would want to risk the damage that could be done to its industry from the UK imposing tariffs on its exports .” Mr . Duncan Smith added : “ When you look at what is going on in Europe the idea that out of that chaotic situation can come any sort of understanding is clearly not right   so we will have to sit tight .” May Expected to Offer EU £ 40 Billion – But Leavers Ask : What Are We Getting in Return ?

Question: North Korean leader Kim Jong Il has put his youngest son in charge of the country's spy agency as a prelude to handing over control of the communist regime  a news report said Wednesday.
 Kim visited the headquarters of the State Security Department in March  along with his 26-year-old son  Kim Jong Un  and told agency leaders to "uphold" his third son as head of the department  the Dong-a Ilbo newspaper reported citing an unnamed source.
 Kim also told department leaders to "safeguard comrade Kim Jong Un with (your) lives as you did for me in the past " and gave them five foreign-made cars  each worth some $80 000  as gifts  the mass-market daily said.
 It said Kim visited a college that educates spy agents last month and made similar remarks there.
 Pyongyang's State Security Department is the backbone of Kim's harsh rule over the totalitarian nation. It keeps a close watch over government agencies  the military and ordinary people for any signs of dissent. It also engages in spy missions abroad.
 The move to put Kim Jong Un in charge of the agency illustrates the elder KimKim's concern about any possible backlash that the father-to-son succession could prompt  the Dong-a said.
 The paper also said the younger KimKim oversaw the handling of two American journalists detained in March while on a reporting trip to the China-North Korea border. The reporters were sentenced to 12 years of hard labor earlier this month for illegal border crossing and hostile acts.
 Kim Jong Il inherited North Korea after his father and founding leader Kim Il Sung died in 1994.
 On Tuesday  the North's main Rodong Sinmun newspaper carried a remark by Kim Jong Il that could be seen as a justification of the father-to-son succession.

Answer:
Kim Jong Il
