Trump just said out loud what had been true for seventy years: The alliance was always for sale. It was always a transaction. The challenge now is ensuring that it is a valuable transaction - and this is where Trump will fail.
The Cold War often feels like the defining moment of modern geopolitics, the era where alliances were forged and the global order was set. But in the grand sweep of history, it is merely a brief interlude in the much longer story of regional dynamics shaped by geography.
At conservative protests in South Korea, it is not uncommon to see demonstrators waving American flags - or even (in)famously dressing up as Captain America. The symbolic act underscores a deep-rooted belief that the United States is an unwavering ally, committed to South Korea, and acting in its interests.
Could the Korea - U.S. alliance end? It seems impossible. Every U.S. official and every U.S. politician says it’s impossible. Strangely, you hear differently here in Seoul. In fact, very differently.
While South Korea still values its alliance with the US, it is taking steps to reduce its vulnerability and prepare for scenarios where US support might not be as robust as it once was.
