Rational, yes, if we wish to lose. A wise man never waits for the snake to strike. Fat Boy Kim has stated he is at war with the US on numerous occasions. In fact, from a legal point, the Korean War never ended. It is simply in a State of Armistice.” That's a fancy way to say “a cease fire.”
In support of that cease fire, and in response to Kims’ (The current whacko, his father, he immediate past-whacko and the original, the Grandwhacko,) promises to not develop fission weapons, we have send the Pyongyang dictatorship billions of American taxpayer's dollars. The result has been nuclear weapon development, missile launches to reach the US, nuclear weapon aid to Iran, and having to watch a young man who clearly wins the award for World's Worst Leader's Haircut.)
The answer s simple. Defang the snake now. (Somewhat limited strike to take out his nuc and missile facilities,
The answer is very simple. Do it now, and in 6 mo nths, no one will care. Wait another 24 months, and Kim will have a real ICBM, and the warhead on top of it.
Bad Karma.
