Bill... I can only read this as you are trying to start something or play devil’s advocate because I find it hard to believe you actually believe any of this...
I believe it quite seriously. I am a conservative and favor peace over war, but not peace at any cost. North Korea is a clear and present danger; far more than Iraq was when we invaded it.
Consider the alternatives...
Do nothing - North Korea implodes through internal military strife over succession, or at the very least becomes very unstable for a very long time. Nuclear weapons available, like Libya's arsenals are even now being looted by terrorists and those who would sell to them; difference is, NK has nukes, biological, and chemical weapons of mass destruction; demonstrated capability via their nuclear detonations. This is not make-um-up Iraq WMD, this is the real thing.
Do nothing - North Korea gets a new leader, and he continues building up their nukes because it is their only real bargaining chip. Military supports him because with this structure, they eat, they get paid, they live well, while the rest of the country (the 99%?) are literally and not figuratively starving to death.
Do nothing - North Korea gets a new leader who decides to negotiate in good faith for peaceful change, including real (this time, unlike 100's of times before) nuclear disarmament and inspection, open borders, free trade, and so on.
Can you think of any other alternatives? If the three above are the basic three possible outcomes to doing nothing, then I strongly advocate attack. First, WE ARE STILL AT WAR. We do not need Congressional approval, we do not need a UN declaration, nothing. We are at war. Second, NK has never honored one of it's agreements with the rest of the world; not one. They practice brinksmanship; that's their game. And it's worked for them. I have a hard time believing they are about to turn over a new leaf. They didn't when the fat dead guy took over from his fat dead guy dad. And third, if we do nothing and they continue to build nukes and sell nuclear technology and weapons to terrorists and rogue nations, one day the USA or the UK will be nuked by one of their bombs. Unacceptable, period. Nuke them now; remove the fangs. End the war. Bring the troops home. Open the borders so their starving millions can be fed. Time to put this nonsense behind us forever. I'm not up for another generation of bat*****crazy lunatics kidnapping movie directors to make personal Godzilla movies (yes, he did that) and selling nuclear technology to Iran. Screw that. End it today.
