The_Viscount posted... Consider SK relies on the US for its military, I'm not sure what they expect to do. It's not SK's military might keeping NK at bay.
If the new leader is planning on investing in SK's military, that might be different... but then SK would also need a larger standing military.
Biden will be strictly worse than Trump when it comes to military expenditures. As for their stances on NK, Trump's willingness to come to the table with KJU was a mixed blessing. Nothing productive came out of the talks, but it might've lessened KJU's need to saber rattle to make himself look strong. And, honestly, at some point world leaders should try to negotiate for reform instead of sticking to the failed policy of isolation, particularly since the isolation policies are dangerous when you have a number of isolated nations who can build into factions -- not that America's leadership ever learned anything from history nor are the guys focused on domestic issues necessarily right for resolving foreign relation problems.
I mean, the US's foreign policy of cutting off nations until they play ball is exactly what's going to lead to an actual world war 3. Commerce and international trade had largely served to calm international relations, because it's much more inconvenient to war with a trading partner than a nation with whom you don't have a trade partnership. Which also comes to the issue with sanctions as a tool, because they quickly lose their value.
Everything you said is wrong, lol
