Japan and South Korea are in the throws of a dispute - and its getting worse. What was a trade war escalated to the security realm last month when the South Korean government announced that it was pulling out of a key intelligence sharing agreement with Tokyo. This agreement enabled the real-time sharing of key intelligence as it related to common threats, including from North Korea.

Needless to say, amid a growing threat from North Korea, which is regularly testing missiles that could reach both countries, this dispute between South Korea and Japan poses a big risk for international security.

So why are two key US allies that share a common adversary at such loggerheads? And what does a frayed relationship between Seoul and Tokyo mean for regional security and international relations more broadly?

On the line with me to answer these questions and more is Andrew Yeo, associate professor of politics at the Catholic University of America. We kick off talking through the World War Two era origins of this conflict before having a longer conversation about the global implications of a dispute between Japan and South Korea.

If you have twenty minutes and want to learn why historical grievances have become hyper-relevant in East Asia -- and why relations are poised to get worse between these two countries, have a listen.

People often ask me what podcasts I most enjoy listening to and top of the list for me is "First Person" from Foreign Policy magazine. The host, Sarah Wildman, is someone I have gotten to know over the years and whose work I have long admired. Each week she draws out from one guest a personal story or narrative that has some broader global significance.It's a great show and if you are fan of Global Dispatches, you'll certain enjoy First Person.
