In the two test launches shown in the video, the "missile" doesn't fly straight nor does it demonstrate ability to be "guided" by the launcher towards any particular target. It's also incredibly slow. There are children's rocket kits that fly significantly faster than this.

The engine and the warhead are two of the biggest challenges in making a missile, in large part because anything high performance is also going to be spectacularly dangerous to manufacture.

Guidance is by a huge margin more important. The best engine and warhead is meaningless without a means of hitting your target.

The Russian revolution is not a good example if you are talking about the October revolution. It cannot be stated objectively that it turned out to be worse, and, in fact, for many replacing the czars with the Bolsheviks led to a lot better living conditions.

Tell that to the 60 million people who died in the Holodomor.

Why not 120 million?

What about the 240 million who died under the tzarist regime?

If you're going to make up nonsense numbers, why stop there?

Which revolutions in the 1900s were started for fun? Unless you're considering CIA backed coups in that count?

Loads, the various attempts to overthrow the Weimar Republic for one, but many smaller, like the Impresa di Fiume. Maybe not “for fun” but largely for justifications that pale in comparison to the suffering they unleashed. Americans ready to go to war because eggs and gas are too expensive, or their trans teen’s top surgery was delayed, might be making similar mistakes. But Americans are good at making mistakes, perh…

> trans teen’s top surgery was delayed

This is in poor taste given there is a bill right now being debated that bans the exact surgery you’re mocking. It also bans trans Americans from participating in gendered sports. You should find a better example.

Agreed. With all of the efforts to make it difficult for trans people to exist in society, it is quite literally an in-progress attempt at genocide.

I disagree. A missile without guidance is a rocket which definitely has its uses on the battlefield.

A missile without propulsion is at best a bomb which doesn't do much good without an aircraft to drop it from

On the defensive side, see perhaps this phased array radar system with a 20km range: * https://github.com/NawfalMotii79/PLFM_RADAR

What a time to be alive. In fact, I think I now have all I need to start a war with my neighbours.

Just be sure to (re-)read your Sun Tzu and Clausewitz first (unlike the current US administration).

These discussions always focus around enforcement and never on alignment. The moat for this stuff historically has never been strict enforcement; it has been that the people who have the know-how on how to do it have nothing to gain by doing it, since they are well-educated and benefit from the current socioeconomic order (they have no motive to change it; rather, they want to climb it). This is shifting. First, econ…

your argument here rests on whether someone with the know how to do these types of things will not be able to find a job in the near future. I’d call this unlikely

There are no few smart, knowledgeable people in the world (perhaps self-educated, perhaps not) who for a huge variety of reasons may be either unwilling or unable to hold a typical job.

I’ll bet most of us here know at least a few people along these lines.

https://www.law.cornell.edu/uscode/text/18/2332g states that just having a system "intended to launch or guide a rocked or missile described in... [description of MANPAD type rocket]" carries life imprisonment. He calls it a manpad and then shows a system intended to launch it. There is no consideration in the law whether he actually plans to use it or ever meant any violence, nor any consideration of whether it viol…

There seems to be a jurisdictional escape clause in the sense that possession without use within the US without the intent to attack aircraft may not fall into interstate commerce. In which case the state law would govern the act. IANAL

IANAL.

Note they started adding the "interstate commerce" in there after the first version of the gun-free school zone act was found unconstitutional. Which then continued on to do the exact same thing when amended.

It's a distinction without difference.

Post Wickard v Filburn, mere possession of something has been found to be interstate commerce even if it's just a plant grown on your own property for your own consumption without ever entering interstate commerce. Note the controlled substance act depends on the same interstate commerce clause but they've upheld federal convictions for simple possession without showing any actual effect to commerce -- instead arguing that they've influenced interstate commerce by deciding to not participate in it and that if people did that in aggregate it would affect interstate commerce therefore it is interstate commerce. Complete madness obviously, but that's where we are.
