North Korea has successfully tested multiple missile launches on a lofted trajectory that demonstrated an intercontinental range. I believe both the hwasong 17 and 18 are capable of hitting the continental United States. Rentry vehicles have been demonstrated multiple times. Accuracy is a bit more of a concern, but with a thermonuclear weapon missing a city by 10 miles is still more than enough to cause millions of c…

DPRK does not seem too have the hydrogen bomb. Fission bombs on the kiloton range are too heavy to be mounted on ICBMs. I will not lose much sleep until there is credible information that DPRK has mastered the fusion bomb.

No, their last nuclear test was estimated at around 250 kilotons, which is indicative of a thermonuclear bomb. That was in 2017

Jesus, I hadn't realized they had come so far. Apparently NK gained the ability to hit the entire continental US with Hwasong 15. The latest iterations are suspected of being designed to contain MRVs or MIRVs, which would completely overwhelm US missile defenses. It is insane that we let them go down this road.

Even they know that if one launched from their end they would all cease to exist within minutes.

This is a deterrent until Kim Jong Un loses his marbles or receives a terminal diagnosis, or until some military commander makes a serious mistake. Now multiply this same risk times fifty or sixty and you’ll see why the major project of the 20th century was limiting the number of countries with nukes.

The title and some of the comments assume it would be something like if you take 15 extra minutes you would just die . When in reality it would just be an increase in cancer risk. If it were THAT contaminated they'd use the AREA CLOSED the article mentions anyways. To be fatal within days you need about 10,000 mSv of exposure. Even with heavy fallout, exposure would probably be around 10 mSv per hour.

Driving in montana before the state implemented a max speed, I'd have my cruise control set at 100 mph. I remember seeing limos pass me like I was sitting still. I miss those days.

Reasonable and prudent is objectively the best speed limit. Going 110 on a dry empty highway? Carry on. Going 110 on I-90 right outside of Billings? Pull over young man, its time for the highway patrol to have a philosophical discussion with you on the side of the road.

110 MPH is never a safe speed for a car on a highway. Crash rate increases exponentially with speed. At 110 MPH you are placing your life and the lives of other road users at risk for no real good reason.

That was just the excuse everyone used to have a go at eachother. Russia didn't want its pan-slavic ambitions to get embarrassed again (as they were with the Austro-Hungarian annexation of Bosnia), France wanted revenge, Austria-Hungary wanted to remind everyone that they were still around and relevant, Germany wanted to establish supremacy on the continent, the UK wanted to curtail German ambitions, and prevent the…

I've seen it described as a powder keg waiting for a match.

To me, the Russian Revolution is The Worst Thing That Ever Happened, and I imagine we'd have a much better world if that match was never lit.

There’s a good chance they fail since our intelligence services are essentially watching everything they do internally in real time.

And a proper failure gives an opportunity to disappear them.

It depends where in Germany. Many parts of Autobahn have local speed regulations.

To be exact: Out of 25,758 km Autobahn in Germany 18,115 km have no speed limit (70.4%) and another 1,608 km (6.2 %) have gantries without speed limit under favourable conditions (construction sites not taken into account).[1] There are also some other roads that are not included in these figures because they are not classified as Autobahn, but Autobahn-like carriageways. Germany has around 3,350 km of them, a few wi…

That's actually a much higher percentage without speed limit than I expected. I wonder if the stretches without speed limit are usually order traveled and thus less experienced. Anecdotally I used to drive between Bonn and Paderborn a lot and the speed limit would only go away once out of the densely-populated Ruhr area.

Everyone makes this mistake -- reducing radioactive fallout harm to just one metric.

In reality, a much larger danger are heavy radioactive isotopes that can be eaten/breathed in. E.g. you can walk in most of the Chernobyl areas, but don't you dare eating anything that grows there.

So you’re saying that if we want to avoid World War 3 we have to get rid of nationalism in Serbia ?

Actually, that was absolutely correct until 1990 or so.

When I was young and the world was filled with anti-nuclear grimness, my father took me aside and told me I had nothing to worry about... until Josef Tito died. I didn't even know who that was. When he had been stationed in NATO, he'd served as squadron planning officer. He'd read SIOP and all the war plans, which he said were all ridiculous scenarios- except for Tito dying and Yugoslavia disintegrating.

He said NATO and the Warsaw Pact would go to war over the civil war. It would be impossible to stop as refugees and fighting would be everywhere and the Soviets would roll in.

He was absolutely dumbstruck how long Tito's grip from the grave kept the country together. When the Soviet Union fell, he said at least it won't be a nuclear war now.
