President Donald Trump is being urged to confront North Korea and also to build up the army which, some say, has been neglected in the Obama years and even before.

He needs to do this as well because North Korea is supposedly getting close to having a usable nuclear force.

This is a crisis everyone has seen coming. That's why Japanese Prime Minister Shinzo Abe has been so desperate to court Trump, visiting him even before the inauguration. As North Korea launched an intermediate medium-range ballistic missile on Sunday, Abe was once again with the president – this time on a golf and bonding trip to Mar-a-Lago, Trump's Florida retreat.

… Pyongyang first demonstrated its ability to detonate a crude nuclear device in 2006 – becoming the only Iraq- or Iran-style "rogue state" to ever get that far. Since then, it has continued to develop not just the bombs but also the missiles to deliver them.

Ultimately, the regime would love to have the ability to strike the continental United States – a prospect Trump has tweeted to say "won't happen". For now, however, there are few signs anyone has a plan to stop it.

The article goes on about North Korea's land-based "nuclear rockets" and the progress it is making in creating and distributing them.

But who is making these claims? One of the only ways to know is to measure earth quakes. America is doing that, but the Pentagon has nearly as many reasons to exaggerate the North Korean threat as North Korea itself.

We don't believe that North Korea has much in the way of nuclear weapons. It may have none at all. Not even the "mini-nuke" that you can possibly pick up in both hands. But with Trump banging the drums for more armament, North Korea has suddenly become a big threat to the United States.

There is no real evidence for North Korea having a large nuclear force. But because we are told it is so, we should believe it. These are the same kind of observations that go back some 75 years to Hiroshima and Nagasaki even though its fairly clear that both cities were firebombed.

Some sort of nuclear device may have been dropped as well, but if it was nuclear device it wasn't a very effective one. Sam Crawford, who ran the post-war nuclear program in Japan has said,

When the bomb went off, about 2 thousand people out of 250 thousand got killed [in Hiroshima] – by blast, by thermal radiation, or by intense x-ray, gamma radiation … You see, it wasn't "Bing" like the publicity here [said]: a bomb went off and a city disappeared. No such thing happened. That was the propaganda for deterrent …

When I came back to this country, I was appalled, from a military standpoint, to find that our major planners in the War Department were using their own propaganda, 100 thousand deaths, Bing! …

You don't hear much about the effects of Nagasaki because actually it was pretty ineffective. That was a narrow corridor from the hospital … down to the port, and the effects were very limited as far as the fire spread and all that stuff. So you don't hear much about Nagasaki.

It makes very little sense that nuclear weapons have been around for 75 years but never have been used. Never as in not once. Except for the supposed uses in Hiroshima and Nagasaki. And there is a good deal of doubt they were actually used then. In fact, they are still basically the same size and shape.
