U.S. foreign policy can be positive-sum, not zero-sum: Jake Sullivan

WASHINGTON -- The U.S. can pursue its own interest while simultaneously looking out for the larger, global common interest, without foreign policy having to be zero-sum, former national security adviser Jake Sullivan said on Wednesday.

Speaking at a webinar hosted by the Carnegie Endowment for International Peace, Sullivan, the chief foreign policy aide to former President Joe Biden, said he was struck by President Donald Trump's "policy of subtraction," that has seen America pull away from the transatlantic alliance with Europe, as well as distance itself from neighbors like Canada.
