Martin Soong (MS): I'm sure you agree that losing precious American intellectual property is an issue, it's a problem. Tariffs though you're probably agree, that's not the way to solve them?

Lawrence Summers: I think there are important issues on both sides. We need to address them in some kind of broad strategic context. Ronald Reagan said about nuclear wars that they can never be won and must never be fought. I confess I have the same view of trade wars. I don't see that the steel tariffs are a prudent bit of public policy. Forty times as many people work in steel using industries as in the steel producing industry, so I think that's a bit of a stop-or-I'll-shoot-myself-in-the-foot kind of strategy.

MS: So you think that the tariffs will backfire then?

Lawrence Summers: I think the risks to the American economy from the steel tariffs are far greater than the risks from the absence of the steel tariffs.

MS: And far greater than the damage that they could potentially cost China?

Lawrence Summers: I don't know what damage they'll do China. I just think that they'll do damage to the American economy even before China retaliates. They'll do damage because they'll mean higher prices in all the industries that use steel where 40 times as many people work.

MS: That must then put the Fed in in a tougher position?

Lawrence Summers: Well I think the Fed is in a challenging position in any event having to read what's happening in the economy, having to read possible inflation pressures, having to read developments in markets. My own view is that the Fed should be very very cautious about hiking rates given that if the economy were to turn down, we have less ammunition than we usually have.

MS: And do you get that sense from Jay Powell's first time at FOMC with the recent decision to hike?

Lawrence Summers: I'm going to let Jay's words speak for themselves and not try to interpret them. I think he did a very solid job.

MS: OK. Let me ask you. It might be easier for me to ask you now that you're out of government, but John Bolton now appointed, also accepted the new National Security Adviser. McMaster is out. We know his views, we know he's a very hard line and a hawk especially on Iran but also on North Korea, how concerned are you?
