Will they start shooting rockets when it gets foggy ouside now?

Historically they've not done that because they know the IDF's response is proportional to the civilian casualties on the Israeli side. Better to wait for clear weather when iron dome is maximally effective.

I'm curious where the tipping point is, where the military response exceeds the financial cost of a political response. It's one thing to have tensions simmering on both sides of a border, it's another that one side feels wronged and is lobbing bombs over the fence.

The fact that they're having to develop a laser defense system to defend against lobbed bombs seems like it's time to reevaluate political solutions.

I will believe it when I see it. Focusing that much light on a small moving object, through layered and moving air, with an intensity to burn through metal would be an achievement. Burning through enough of that metal to degrade a falling rocket (as opposed to during boost phase of flight) is even harder. For all the talk about cost reduction, have a look at what realworld laser armor costs. Painting the nosecone of…

It would need to pack the energy of a stick of dynamite (1 lb explosive weight) into a short burst of light.

This tech will be the end of MAD and the start of WW3. The only thing holding back current super powers from direct confrontation are ICBMs and MAD. Once they can be reliably shot down via lasers, then full scale war is much more likely. I understand the current tech is for much slower, much lower rockets and cruise missiles. But the tech will evolve and get better. Israel is the current test bed for high tech defens…

MAD was a dumb idea in the first place. Everybody has known, since the first world war, that a major power confrontation is very likely to end your nation, even if you win . The French were so demographically destroyed they literally could not raise an army to fight in the second world war. The British were so broke their empire collapsed. The Russian empire, the Austrian empire, the Ottoman empires all collapsed int…

> he French were so demographically destroyed they literally could not raise an army to fight in the second world war.

This isn't true at all. The French army at the start of WWII was over 5 million men, one of the largest in the world. It suffered from bad luck and being led by morons, but it certainly existed.

Per your other point, WWII made the US and the USSR global superpowers for half a century, and the US especially sacrificed far less than anyone else to get it. War is sadly not always a losing proposition, even total war.

But would it not be possible to build missiles that can intelligently alter route upon detecting detection ? I recall once working on a auto guided industrial machine based on Motorola 68000 microprocessor that could figure out how to route itself to its destination. So unless you can detect and eliminate the missile almost simultaneously, an intelligent missile could throttle it's velocity etc. to avoid predictable…

This is again a money play here, after all everything is a money play. Iron Beam (this system) is designed to intercept simple rockets, artillery, and etc for cheap. The total cost per shot is estimated at 2000USD overall (including life cycle of the parts, laser, etc) compared to 100000USD for Iron Dome missile alone. It is even more for more advanced stuff like Arrow 2, Arrow 3, or David's Sling (all, including Iro…

Automated counter-battery in addition to AD would be an interesting extra layer of deterrence.

The space lasers were real /s (in reference to the Republican congresswoman who blamed the California wildfires on Jewish space lasers: https://nymag.com/intelligencer/article/marjorie-taylor-gree... )

It really surprises me that so many people who have seen UFO reports all their lives cite this as nothing but humorous stupidity from a politician. People who follow satellite data in order to understand global patterns of earthquakes and weather saw what looks like beams from unknown sources hitting areas that then caught fire. As with anything else this is very likely to be some kind of sensor or transmission glitch that simply needs to be analyzed in detail to find some mundane explanation, but it is worth acknowledging that the whole business emerged not from the political foolishness that got attached to it later but from hobbyists trying to explain genuinely peculiar data. Even when people talk about UFOs or space lasers it is worth taking in and trying to explain the actual data.

Ill never forget when the Iron Dome was first rolling out, this rocket researcher on the internet said it couldn't be done. He explained it pretty well, and I was convinced. Search google for Iron dome doesn't work (looking back to 2010-14) And yet, it does work (mostly).

So basically what I'm saying, this stuff is hard, and few people in the world can even verify your claim, never mind have access to the tech or AI behind it. But i'd bet with the Israelis.

...and then what. What will they do when the rockets get faster, shinier, more erratic in flight...or any of the other things mentioned on this thread? I'm not going to pretend I have the solutions to the Arab Isreali conflict, but this is at best temporary. My best guess is the long term solution (if there is ever one attempted) will be more related to why people are motivated to launch rockets at their neighbours.

As long as EMPs are viable MAD is still in effect.

An emp would knock out electrical grids.... sure... But that isn't annihilation... Say russia installed this in major cities (rural is acceptable loss), then manufactured super sonic nukes that could deliver a strike in under 5 mins... or even a minute... they could strike many of our nuke sites (not all because of subs) but our major military operation bases, then we strike back from subs, but these take them all ou…

>there's some fallout from atmospheric explosions which may be as bad, but maybe they hoist huge fans to blow it south to the Ukraine or another enemy state...

This was in fact precisely Vladimir Zhirinovsky’s idea in 1991 to stop the Baltics from seceding
