Orsini ha scritto un articolo delirante contro di me e @aa_gilli. L'articolo invece di rispondere a critiche fattuali che io e Andrea, in due thread diversi, abbiamo avanzato verso sue affermazioni prive di fondamento, si lancia in una invettiva verso di noi.
Orsini cerca poi, maldestramente, di riproporre nuovamente la sua speculazione per cui i sistemi di difesa iraniani riuscirebbero ad abbattere un F-35 a 300-400km di distanza.

Mi è stato girato questo video del professor Orsini, secondo il quale la limitata risposta Iraniana all’attacco Iraniano è spiegata dal fatto che l’Iran ha sistemi di difesa antiaerea che possono “colpire gli aerei Israeliani a 300-400km di distanza, cioè è in grado di colpire...
... sia missili balistici di lunga gittata, sia i droni, sia i caccia di quinta generazione, cioè fondamentalmente gli F-35 americani, che sono i caccia più avanzati di cui Israele disponga.”
Non so neanche da dove iniziare. Se non fosse tutto deprimente, sarebbe divertente.

We live in an age in which nobody admits being wrong, so quite remarkable to read someone doing it. In this regard, I have a couple of points.
First, the paradox about the debate about missile defense and the F-35 (regardless of which side you take) is that the unconventional thinkers soon created a new orthodoxy.

Italy squandered 135 billion (yes, with a b) with its measures to promote growth during the pandemic. corriere.it/economia/finan…
In particular through the "Bonus 110" which literally covered 100% of costs for refurbishing houses and left some chips for banks. One of the most regressive fiscal measures to date. And one which is likely going to restrict any fiscal leeway for the next years.

Last night I read the Seymour Hersch's piece. I am probably late to the party and I am sure much more competent people than me have already take a stab at it, but here I wrote down a couple of points about the part on the activation of underwater mines.
Spoiler: it doesn't makes much sense.
If you haven't read Hersch's essay, here you can find it. To me it reads as a great Hollywood script, more than an accurate account of events. Below I explain why. seymourhersh.substack.com/p/how-america-…

Given the attention to the B21, here I have listed some articles and books that I found useful when I wanted to understand #stealth technology (or "low observable", LO).
First and foremost, to understand stealth you need to have at least some general understanding of radar (and more generally, sensors). I wrote a thread some time ago with some references
Over the past months, air defense has received significant attention. In case you'd like to understand more about radar, jamming, decoys, surface-to-air missiles, and the like, here some sources I found very useful.
These are the works I have used for a lecture in a class I teach at @CSS_Zurich of @ETH_en with @alexbollfrass, @HerzogSM and @NinaSilove.

Il mite avvocato pugliese è uno che ha chiuso in casa gli italiani a colpi di DPCM, trasformando le FAQ del ministero dell'interno in fonte di legge, lasciando gli italiani in balia dell'arbitrarietà delle forze dell'ordine, mentendo circa le raccomandazioni del CTS,
per poi cercare di insabbiare il tutto secretando i verbali. Se ci fosse una nuova ondata di COVID e Meloni/Salvini facessero una frazione di queste cose, voi gridereste (giustamente) alla soppressione delle libertà costituzionali e della democrazia rappresentativa.

Russia did not conduct suppression/destruction of enemy air defenses prior to launching the ground invasion of Ukraine (some say for doctrinal reasons, other say for capability limitations). Now on, the Ukrainians will be targeting Russian radars. forbes.com/sites/davidaxe…
HARM (high-speed anti-radiation missiles) are missiles that lock on a radar wave and home towards its source, with the goal of destroying a radar. They are "high-speed" because their goal is to get to a radar outpost before it relocates.

The first edition of Euro-Summer Workshop on Military Operations and Strategy at @Hertie_Security is over, let me thank again @mephenke and @Hg_Meijer for all the work they put behind it and for having made it possible.
Our aim is to provide PhD students & recent PhDs based in🇪🇺with exposure to topics such as mil ops & strategy they have little opportunities to learn in their home institutions. So that they can contribute to Euro academic and policy debate on pressing defense and security issues

Italy has a debt to GDP ratio of 150%. This means that minor increases in interest rates entails massive increase in cost of debt financing (today interest rates are above 3.3%, which means that Italy will have to spend about 5% of its GDP for interest rates).
(to put in perspective, fiscal policies set by Maastricht agreements required countries to keep government deficit below 3% of GDP; with cost of debt at 5% of GDP, if government spending = government revenue, you are already at 5% deficit of GDP).

There seems to be some misunderstandings on submarines: nuclear-powered submarines are NOT quieter than diesel-electric. The opposite is true. A nuclear reactor cannot be shut down. Electric batteries can.
Moreover, electric batteries do not generate machinery noise; a nuclear reactor does. There are variations in machinery noise (US subs are quieter than Chinese one) but the point stays: 🇸🇪🇩🇪🇯🇵 AIP subs are the quietest in the world

@divert_thruster I don't know the precise answer, some programs during WWII (e.g., B-29, Manhattan project and radar) required the applications of some of the principles of systems integration. In case you don't know it, this article provides an overview of WWII programs jstor.org/stable/3106953…@divert_thruster Definitively, between the end of the War and 1960, it became inevitable - with B-52, Skipjack, Polaris, air defense systems, ICBMs and space programs. On this, you will really like this book, fascinating: amazon.com/Systems-Expert…

For those who are interested in understanding what is happening with Italy and what is the problem with the European Union, here I have put down some scattered thoughts.
To start, Italy is a kleptocracy, where key insiders have huge benefits, while outsiders struggles to get the (small) leftovers.
