[Q]: Tanner Roark  will take the mound with the Nationals facing elimination in Game 4. (Jeff Roberson/AP)
CHICAGO —  Tanner Roark  was born and raised in Wilmington  Ill.  which is southwest of Chicago  which means  he  grew up closer to Comiskey Park than to Wrigley Field. But geography didn’t impact baseball team allegiances in the  Roark  household.  He  grew up a die-hard Cubs fan like  his  mother and siblings  diverging from  his  father’s loyalty to the White Sox and the Cardinals.
“Growing up  yeah  there was always some trash-talking in the house between us and my dad ”  Roark  said.
On Tuesday  barring rain   Roark  will find himself on the mound at Wrigley Field  the ballpark he visited countless times as a fan  to face the Cubs. It won’t be his first start there; he has four on his résumé and appeared in another game out of the bullpen. But none of the previous outings carried the same weight Tuesday’s will place on Roark’s right arm: Game 4 of the National League Division Series with his Nationals facing elimination.
“It’s pretty surreal to pitch in Wrigley  and just the history that they have here and everything ”  Roark  said. “It’s very exciting  and I’m anxious to get out there.”
 Roark  hasn’t pitched since the Nationals’ regular season finale on Oct. 1  when  he  allowed two runs in an inning of relief against the Pirates  and  he  hasn’t started a game since Sept. 27.  He  lasted 4 2/3 innings that day  surrendering six runs on seven hits to the Phillies. But  Roark  was significantly better before the poor finish;  he  had posted a 3.39 ERA in 57 innings over  his  previous nine starts to rebound from an inconsistent four months after  his  stint with Team USA at the World Baseball Classic made for an unusual spring training.
“ Tanner  didn’t have many innings coming out of spring training  and that kind of got  him  behind the eight-ball  so to speak  because you know   he  didn’t have the innings ” Nationals Manager Dusty Baker said. “ He  was with the WBC and  he  didn’t pitch very much. And so things get in your head when you’re used to getting guys out and all of a sudden you’re not getting them out. So it’s a new season now for Tanner  brand-new season  and this is what people are going to remember you by.”
“ Tanner   you know  is a guy that you would like on your side if you’re in an alley and you’re in a fight  because you know  Tanner    he  has that warrior mentality ” Baker said. “ He  doesn’t make any excuses or alibis.  He  just goes out and pitches  and  this guy  has not had an easy road  you know  from the beginning to get here. We feel very comfortable with  Tanner  on the mound because you know  he ’s going to fight tooth and nail and do everything  he  can to win the ballgame for you.”
 Roark  recalled 300 people from Wilmington congregated in a section in right center field for  his  Wrigley Field debut in 2013.  He  doesn’t expect that again Tuesday.  He  hasn’t been hounded for tickets. Five relatives   his  wife  and their two children will be in attendance to watch  his  biggest game of  his  career.
“They are good about getting their own tickets ”  Roark  said  laughing. “Which is very good on  me . It’s a lot less stress that I have to worry about.”

[Q]: MURDEROUS  thin-skinned and in possession of nuclear weapons  the North Korean dictator   Kim Jong Un   has one good deed to  his  name:  he  has united America and China. Max Baucus  Americaâs ambassador to Beijing until January 2017  recalls the Chinese president  Xi Jinping  privately expressing âdisgustâ at Mr Kimâs reckless pursuit of nukes and missiles to carry them to other continents. Mr Xiâs frustration with North Koreaâs hereditary despot stands out as âthe strongest statement that I have ever heard Xi makeâ  says Mr Baucus. China has never sounded as closely aligned with America when it comes to using sanctions and diplomatic pressure  in a last-ditch bid to change how Mr Kim calculates his regimeâs interests.
Unfortunately for relations between the worldâs two biggest economies  China will hate the next steps that America is likely to take on North Korea. Evan Medeiros  until 2015 the senior director for Asia in Barack Obamaâs National Security Council  says that when the Chinese accuse America of refusing to engage in talks with the regime  this is largely âposturingâ. But behind it lies a truth  that âsanctions wonât stop North Koreaâ. When battling the proliferation of the deadliest weapons  sanctions are always in a race with technology  says Mr Medeiros  now with the Eurasia Group  a consultancy. âKim Jong Un is close to grasping the brass ring. We have probably lost the race and need to think about deterrence.â This could include deploying new missiles and missile-defence systems in South Korea and Japan  and perhaps another aircraft-carrier in the region.
Still  cold-war theories of deterrence are being dusted off  with such jargon as âsecond-strike capabilityââthe certainty that a country attacked with nuclear weapons can retaliate massively. Douglas Paal  a senior Asia hand in the Reagan White House and both Bush administrations  approves of the Senate plan to place more interceptors in Alaska  in part to gain leverage over China. âWe need to layer up more missile defence. China needs to see that their second-strike capacity is really deteriorating  which hurts them.â Mr Paal  who runs the Asia programme at the Carnegie Endowment for International Peace  a think-tank  is in frequent contact with envoys of governments including Chinaâs and  recently  North Koreaâs. He concedes the need for talks with the  Kim  regime  alongside containment and deterrence  but notes that in previous negotiations  North Korea wanted an end to American defence alliances in Asia and to Americaâs troop presence in South Korea: âSo we canât get there.â
A policy of containment would not just strain relations with China as new American weapons bristled in Asia. Global non-proliferation regimes would be tested  not least because a North Korea facing crippling sanctions might see selling nuclear technology as a lifeline. Perhaps Chinaâs greatest nightmare involves Japan feeling compelled to build nuclear weapons (it could quickly develop the technology). A Chinese build-up of warheads in response could result in India and then Pakistan increasing their stockpiles. The unity fostered by  Mr Kim  may thus prove short-lived. If  he  builds the arsenal  he  wants  China and America will be sincere in their shared dismay. But if America then prepares to contain him  a whole new Sino-American stand-off may begin.

[Q]: On November 16   Tesla  unveiled  its  long-anticipated foray into the $726 billion world of trucking: A heavy-duty  all-electric rig aptly named “Semi.” The truck itself is wildly impressive in our opinion—a 500-mile range  projected fuel savings of $200 000  and the industry’s most advanced levels of automation—but what excites me the most  really  is the opportunity this truck signifies: The start  as I see it  of a once-in-a-lifetime radical shift in our trillion-dollar transportation economy.
As I have written about before  we are currently entering a period of a rapid change in our transportation systems. And as I see it  it’s the innovator’s dilemma playing out in the wild: Incumbents like General Motors are moving too slowly to adapt to an all-electric future—wasting billions of dollars on stock buybacks—while upstarts like  Tesla   unencumbered by legacy business models  are forging a path into a clean  fully-electric  fully-autonomous future. (GM has spent almost $17 billion in the last several years buying back its stock  three times what  Tesla  has spent building Gigafactories—but I digress.)
I spoke with Perry at length recently regarding  Tesla ’s ambitions and challenges  the future of transportation  and his macro perspective on the innovation taking place right now in the trucking ecosystem. Below is an edited transcript of our conversation. (Full disclosure: Worm Capital is long  Tesla  and all views are Perry’s alone.)
Worm Capital: This week  we're seeing  Tesla  come out with their Semi  and clearly Elon Musk has talked about creating an all-electric  autonomous future. So  existentially  what does this mean for the trucking industry over the next 10  15  20 years? How do you see it evolving from what it is today to what it will be in the future?
