Uhm I am pretty sure that's not how it works. Where would the drive against the Earth's rotation come from? If you put a rock on a length of string and swing it around your head then when you let go it doesn't keep orbiting you, it goes out in a straight line 90 degrees from the line of the string at the time of release. Same principle. You'd need to clear the atmosphere but I think the principle is sound. You'd also need to turn around and come back down at the right time. You are (somewhat) right but the examples you are bringing up don't really explain what you are arguing. The reason the rocket doesn't come down at the same spot is that in order to stay over the same spot it would have to rotate around the center of the earth faster with every bit of altitude gained. But it keeps the same rotational speed it had at liftoff. That has nothing to do with in or out atmosphere either, if you want imagine the atmosphere doesn't exist and come out at the same location. The effect is rather small though over reasonable altitudes (like 100km) so you would still hit rather close from your starting location. Of course you could go further out to increase the effect but then you might as well just travel towards your target like a proper ICBM.
It is slightly more complex than that (though not a lot). It is about angular momentum, which is a conserved. (You can see this phenomenom prominently in ice dancers. If they do a spin, they start with their arms wide out, them pull them towards themselves and spin faster) Thus, if you go further up, to stay at the same angular momentum your velocity tangential to the surface of the earth needs to slow down. So not only would you fall behind the earth even if you stayed at the same speed, as you have a longer way to follow, you also move at a slower speed due to conservation of angular momentum (Of course this can be counteracted by, for example, firing your rocket in a slightly different direction).

Makes sense. I am assuming again the effect will be rather small though if you go from a radius of 6400km to 6500km right? So you would still come down fairly close to your starting location.
In the end I think it's easier to just aim your ICBM at the enemy Kwark

As far as i know, normal ICBMs go up to 1200km over the ground already. And at that altitude, the difference is definitively relevant. I am too tired to do exact calculations now.
What he "Ballistic" in ICBM means it exactly that you don't aim it at the enemy, you lob it up into the sky and make it fall down onto the enemy.

They are aimed as much as modern artillery is, which is a lot. Modern nations can be very accurate with them relative to their size. North K. much less so, but they are not really about accuracy anyways.

So what's the difference between artillery and ballistic

Artillery is not guided... it is just a projectile like a golf ball. Ballistic missiles are only guided during a short period of time during their flight. Guided missiles are aerodynamically controlled for their entire flight.

Both are guided. You cannot have a 500 kton warhead unguided. A ballistic missile has a ballistic trajectory. It will go out of the atmosphere, then fall down again, and i wig have wings to fly. A cruise missile follows the surface on a parallel trajectory, using aerodynamic lift.
Modern artillery can shoot guided shells.

North Korea has executed its army chief of staff, Ri Yong Gil, South Korea's Yonhap news agency reported on Wednesday, which, if true, would be the latest in a series of executions, purges and disappearances under its young leader.
The news comes amid heightened tension surrounding isolated North Korea after its Sunday launch of a long-range rocket, which came about a month after it drew international condemnation for conducting its fourth nuclear test.
A source familiar with North Korean affairs also told Reuters that Ri had been executed. The source declined to be identified, given the sensitivity of the matter.
Ri, who was chief of the Korean People's Army (KPA) General Staff, was executed this month for corruption and factional conspiracy, Yonhap and other South Korean media reported.
Yonhap did not identify its sources. The source who told Reuters the news declined to comment on how the information about the execution had been obtained.
South Korea's National Intelligence Service declined to comment and it was not possible to independently verify the report.
The North rarely issues public announcement related to purges or executions of high-level officials.
A rare official confirmation of a high-profile execution came after Jang Song Thaek, leader Kim Jong Un's uncle and the man who was once considered the second most powerful figure in the country, was executed for corruption in 2013.
In May last year, the North executed its defense chief by anti-aircraft gun at a firing range, the South's spy agency said in a report to members of parliament.
The North's military leadership has been in a state of perpetual reshuffle since Kim Jong Un took power after the death of his father in 2011. He has changed his armed forces chief several times since then.
Some other high-ranking officials in the North have been absent from public view for extended periods, fuelling speculation they may have been purged or removed, only to resurface.

Kim Jong Un is going to run out of generals at this rate. And probably get himself coup'd in the process.

Kind of shows how shaky his hold on power is. He is nothing compared to his grandfather or father even. And given how each generation's ranking is lower than the previous person's, that is no surprise.

It looks simple to me. He has no son, only a daughter, has already been in power 5 years (his father was in power for 17 years), so it might be optimism on my part, but I'm pretty sure there won't be a 4th "Kim" ruling North Korea - this is the last one. Whether he dies just from being a 130kg asshole, or from someone taking the chance to shoot him (again, possibly being optimistic, but hopefully getting replaced by someone less hard-line than him, which seems likely). I think we can say that government is on the way out. I wish the current administrations were as competent as the previous ones in dealing with that country.

This kind of thing is business as normal in a Stalinist state. Stalin used to do this exact shit. If one of your generals has a late night meeting with the chief of police then it may be a social call but it may also be planning a transition following your death so you need to have one or both shot. One man can't hold it all together, it is necessary that every member of your pack of strongmen is trying to sabotage or undermine every other man to fight for second place. If a faction forms then it's over, if the police won't drag away a general or the army won't drag away the chief of police then you're fucked.

Well couldn't his daughter run the country? Or maybe after Kim dies the US can help north korea implement freedom and democracy

He has brothers / sisters as well iirc. They won't die out any time soon.

They aren't candidates for rule - for various reasons none of them are in inner political circles. I discount it being viable for the leader of that country to be a woman, but I could be wrong. My main point is the father/son lineage doesn't have a future now.

I'm not very knowledgeable about the North Korean situation but they would need someone to succeed him right? I would assume they'd go for a family member even if he's only a figurehead.

The ones holding power after Kim Jong un dies whoever that may be.

I believe one of his siblings (the eldest, maybe?) defected to Japan or some shit like it. Or was it ran away to visit Tokyo Disneyland? Something that insane would probably be more suited to that family.
Chief of staff seems to be a dangerous occupation in NK.

South Korea pulls out of Gaeseong complexSouth Korea started withdrawing workers from the Gaeseong Industrial Complex in the North, Thursday. The government announced Wednesday it would shut down operations at the inter-Korean complex in the border city of Gaeseong, as a countermeasure following a nuclear test and rocket launch by Pyongyang. "The government is seeking to withdraw South Koreans from there as soon as possible," a Unification Ministry official said. According to the ministry, North Korean workers did not show up at the complex Thursday. [...] The move to close operations seeks to cut off Pyongyang's source of hard currency amid international calls for stronger sanctions, following its nuclear bomb test on Jan. 6 and long-range rocket launch this week. [...] Source
No mention of it being a permanent closure, so however long this one lasts will depend on what NK does for the next two weeks.
