We don’t have a particularly good record over the last few decades, either. Everything we’ve tried has fallen apart.
I am tired of spending blood and treasure to benefit ingrates who trash the whole thing a few years later.
I am tried of our troops being forced to fight with stupid rules of engagement.
We should tell the South Koreans, and Japanese (and the PRC, and the Russians) that this is their problem; if we are attacked, or otherwise forced to intervene it will be an extinction event for the North Koreans. We can assist, but we won’t take the lead.
To further emphasize this, we should start pulling troops out of South Korea.
