Regarding a possible war with North Korea, there are issues in that much of that countries military defense and offensive weaponry is under ground. And it will be necessary to have ultra-bunker buster weaponry. Of which these ordinances may not be sufficient although probably will due to the caving in effect of seismic level disruptions from such bombs;

and so therefore I propose a small 1-2 Mega Ton Nuclear weapon on this type of bunker buster. Why? So it can penetrate underneath mountains of bedrocks without failure to eliminate primary targets. We know which regions these weapons are and where they are facing. It appears they are facing Japan, South Korea and what they believe to be suitable long range three stage ICBMs at the US. Can these reach the US? Oh, probably, probably not with any excellent accuracy, but that is not very funny now is it? In the case of the United States using Tactical Nukes or Bunker Buster nukes on the areas of bedrock under which the North Koreans have 144 MM cannons, which can fire about 400,000 rounds in about 8 minutes or so the North Koreans say. This threat alone is why they are obstinate and willing to be so bold as to play hardball with the US in trade for money (extortion) to dismantle their nuclear warhead manufacturing and exporting business. They have nuclear generators and can process spent fuel rods to make weapons. They are planning on this and have probably already done some. This is an international terrorist threat of a different kind, blackmail. If we negotiate there will be others in the future including those we pretend to be our current allies. Should the US prevent war by negotiation with those who have no intention on fulfilling their end of the bargain and have interest and financial desires to sell these nuclear warheads to our enemies, or terrorists of the current kind. Is our intelligence good enough to insure no nuclear weapons leave the country, are we willing to put American Lives in limbo of that question? If North Korea wishes us harm they have allies in those other rogue nations and Islamic groups and they would not fear using such an alliance to defeat us. There is hatred and mistrust on both sides. If we are to strike first to spare our Allies, such as South Korea, which is certainly an option, then we must do so by unleashing an attack, which would render all other military assaults in the past minor in comparison. Such underground fortified offensive and defensive weapons include such weapons similar to the NAZI railroad cannons with Krupp barrels that hit Paris from over 35 miles away. Specifically some web sites and military personnel believe that they could actually hit downtown Seoul South Korea with over 400,000 rounds within 6 minutes. The problem is also that we have substantial personnel on the border with South Korean forces. To penetrate these underground facilities is possible. However we have been studying other weapons using sound, ELF and other secret stuff, which maybe better than tactical nukes on bunker busters such as this continued project.

Folks this would literally do the project and get it done no doubt, but the attack and first strike must be at a time when proper wind currents and jet stream prevails for fallout wind patterns. What if N. Korea attacks first? It is a time bomb and they would if they felt it was an option and that they could break our backs and will. Nuclear Bunker Busters if many were used would no doubt generate a tremendous amount of very heavy radiation, most of it falling on South Korean and Japan. If the winds were different the fallout could well go to the NW over Unggi and Osong, which is why Russia has evacuated all nonessential personnel from that area. And that is only considering their artillery. North Korea nuke sites are also and obviously underground, as are most of their military equipment manufacturing factories. This is known and it is stated by them and in military intelligence reports, hell it is even in the Tom Clancy Op Center Series. To be effective, we would literally have to nuke the entire area and then send in the Marines along with the newest of technologies to insure our allies do not get killed or slaughtered. We know that in 1998 North Korea fired a missile over Japan. It had a dummy warhead, and it was designed to send us a real message to the world that North Korea was strong enough and able to retaliate incase of war the homeland of the United States. Such a warhead aimed at Alaska is feasible and proven by the North Koreans and realize this is real and this is serious. This was in 1998 so doubting that they could hit targets in the US inland would foolish. Thus those liberals who doubt the need for a complete missile defense system are wrong. We need it. So if North Korea has six to eight warheads now, then Von Clauswitz
