[Colonel Kangaroo]

As much as I despise Graham, in this case he might be right. Can we really let Kim and Co. have the ability to deliver nuclear warheads onto American cities? Is hundreds of thousands of dead Koreans worse than millions of dead Americans?

But what incentive does Kim have to commit suicide by such an attack on the US? For all their supposed irrationality, the Kim family has never crossed that line in 70 years of rule.

[Reily]

All Kim is doing is “posturing” to get another influx of food, goods and funds to keep regime collapse from starvation from happening. His nuclear program if it ever actually achieves fission is just another aspect of that.
The West plus China will have the dilemma of allowing unprecedented starvation to occur in the North (with the accompanying instability!), we or the Chinese end the regime & get a short but unbelievably bloody war on the peninsula (with most of the blood Korean blood!), continue to buy him off. It will be the third option unless somebody miscalculates.

Never crossed the line?

Attempted assassination of SK President Park?
The deliberate sinking of SK naval vessel?
Artillery strikes against SK territory (offshore island)?
Attacks on SK fishing boats?
The killings of American Soldiers patrolling the DMZ unarmed?
Pueblo Incident?

Look, I’m not sure that we have any alternatives at this point. But I’m just pointing out where NK has cynically crossed the line on numerous occasions.
