WI: Pueblo Incident Had Occurred in a World Without the Vietnam War

If (disregarding butterflies and all that) the USS Pueblo incident occurred in a world where the US wasn't busy with Vietnam, would America have taken a harder line with North Korea (either in terms of measured reprisals, rescue efforts, or even a general escalation)?

Realistically, Best Korea may have passed on that provocation with no Vietnam war.
 
Second Korean war, here we come! Even Degualle's France, wanted to support Park's regime. A far greater international support, than South Vietnam under Thieu or Ky.
