I gave a reference earlier, in case you missed it.

On June 28th 2010, the US 7th fleet put on a “show” to intimidate China and North Korea. They simultaneously surfaced three nuclear missile-equipped subs, the USS Michigan in Pusan, the USS Ohio in Subic bay, Phillipines, and the USS Florida, by Diego Garcia. These are “Ohio” class subs each of which carries 7 Tomahawk missiles each with multiple warheads capable of taking out multiple cities on distant continents. Prior to this event, these subs have never surfaced in public, they are always on the move under water. And in case you’d like a very reputable source for this, check out the webpage of the commander of the 7th fleet:

On July 24th, North Korea reacted to the intimidation attempt by declaring war. Who says? Reuters says.

While you haven’t been noticing, this show of force has been continuing back and forth between the US and a number of countries it has differences with. Launching a missile west of Los Angeles is small change compared to some of these events, but it is consistent with recent history, and it reminds certain other countries that we have the wherewithal to take them out whenever we care to. Why would you be surprised if the air force says “Missiles? what missiles?” They’re COUNTING on your ignorance of current events and assume that you will accept the explanation that it’s just swamp gas… or contrails… or whatever. In other words, don’t worry your pretty little head and let the big boys handle international policy.
