Kim Jong-un (of North Korea) has been fervidly pursuing nuclear weapons. In fact, he very recently announced that the rogue nation has now acquired them.
Just a couple of days ago, Charles Krauthammer--on Fox News--had a rather trenchant observation, I believe.
He suggested that there are only three possible responses to this:
Response #1: Launch a pre-emptive war. Although this may, superficially, seem like a decent option, the fact is that Kim Jong-un would almost certainly respond by invading South Korea; and that would provoke a response from Washington. Put another way, we would almost immediately be embroiled in a land war on the Asian peninsula--complete with (many) American casualties.
Response #2: Do nothing. In other words, just hope that our ABM system works as advertised.
But if it does not, Los Angeles and San Francisco might soon be reduced to cinders.
Response #3: Announce that we look favorably upon Japan's pursuit of nuclear weapons. This might just alarm the leaders in China--which, of course, is North Korea's client--and thereby provoke them into doing something, to rein in their puppet.
Of the three options, Option #3 does not seem to have a downside.
But what do others think?
