The U.S.？South Korean alliance has played an indispensable role in maintaining peace and stability in northeast Asia. Seoul has also been a stalwart ally in providing troops for security and peacekeeping operations far from its shores. Maintaining the alliance as part of the broader bilateral relationship is critically important for achieving U.S. strategic objectives in Asia. There will be differences in views on the policies and priorities of military and diplomatic policies. At times, these have seemed insurmountable and relations were severely tested. But the alliance always prevailed and will do so again. Both countries’ well-being and security depend on it.
