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.

Baby steps ... with a few more contributors, this could be turned into, say, a $500.00 missile that works quite effectively.

Watching the video I immediately thought of the SNL skit: https://youtu.be/FaOSCASqLsE?t=141

If I am understanding what I saw, for all the work on the canards, the propellant runs out immediately leaving it to tumble in air,

That being said, I agree that it's a prototype and all that entails. I agree that it can (and probably will be) improved upon.

it doesn't really matter in the end because the human species will one day be extinct. would the chechens be in their position now had they never fought? impossible to say, counter-factual conditionals are all unconditionally true. though i'm not sure why you'd assume so...

In exchange for two brutal wars they got 9 years of de facto independence. That's not even very long. You dont need counterfactuals to ask if it was worth it or compare 9 years to the age of the universe. Armed revolutions are often lionized and glorified because they form part of most countries' national mythos - the binding agent holding together most national identities. But, the ugly truth is that most of them ar…

yes you do.

to say something was bad to do is to say it would've been better to have not, and that is a counterfactual.

Everyone with the “only solution is revolution” mentality needs to read this comment. Anyone salivating over/romanticizing armed conflict has never experienced it and can’t fathom how awful it is. I know I can’t, and that’s why I don’t want to find out.

nobody needs to read a comment, tbh, any comment. revolutions are like earthquakes or pandemics: created by forces beyond our control and a matter of when, not if. people romanticizing or anti-romanticizing armed conflict online doesn't even enter the frame .

I think the last couple of elections have shown us how powerful online discourse can be. I don’t think it makes sense to pretend internet discourse doesn’t bleed heavily into the real world. Look at the influence QAnon, for instance, has had on the MAGA movement and the Republican Party at large.

Yes, they have shown that. I don't understand your question about my "line", you'll need to be more explicit.

I think OP's point was rather obvious: carpet bombing is not what defines an atrocity. Russian conducted ethnic cleansing campaigns in Ukraine without carpet bombing too.

From my experiences with the YPG in the Syrian Civil War --- You'd be surprised how many people that have seen combat absolutely loved it. There was one guy that would go in a state of ecstasy while being shot at, literally expressing happily "ha ha they try to shoot me" and this is a guy who had seen many of his comrades die. Once you accept you are dead it's actually far less mundane than normal life, while at the…

I think the point of the hurt locker was to show us how unhinged that existence is, at the end of the day.

Anyone salivating over/romanticizing surrendering to a dictatorship hellbent on committing genocide has never experienced it and can't fathom how awful it is. I know I can't, and that's why I don't want to find out.

So there are only 2 stark options?

> talking about "your line" is way too simplistic

I think you're showing some despair in trying to justify wars. Bombing campaigns aren't a source of good, specially when the agressor is very vocal in how they have no plan or intention to safeguard the people's best interests.

Then there's the fact that it's quite likely the war was started as a desperate attempt to silence and divert attention from the Epstein scandal.

i think exactly the opposite and your comment literally made me laugh out loud, but there's a wide range of views out there.

They are using white phosphorus on populated areas in South Lebanon. That's as vile as one can get.

I have no idea where you came up with that. White phosphorous has over a century of use in industrial warfare. It's widely used as incendiary weapon even in anti-personnel roles. This is direct violation of the Geneva convention.

You can't argue this fact away by claiming it a reddit meme.

Exactly. Revolutions are awful things that are only defensible if the conditions are brutal enough. And even then, there has to be the caution that the revolution can be co-opted by infinitely worse people than those that were overthrown (take the Russian revolution, for example)

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.
