Traveling to the U.S. this week for his second summit with U.S. counterpart Joe Biden, South Korean President Yoon Suk-yeol aimed in part to boost his popularity with a public that increasingly wants Seoul to have more say in U.S. nuclear weapons use — or even its own bomb.

But following the release of the summit outcome on Wednesday, experts are divided about the efficacy of the new nuclear consultation framework that the two leaders agreed to and whether it will satisfy South Koreans who have called for an indigenous nuclear weapons program.
