Tiny Israel can do way much more than Iron Dome... Ever heard about Arrow-3? US MDA head was in awe and declared "We have nothing like this!!!"
France already lies about the real extent of its nuclear arsenal...
58 ASMPA-R, then, 4 submarines, 16 [stealth] SLBMs per sub, 10 MIRVs per SLBM... It doesn't sounds like around 300.... Dismantlements are published, I remember well about the Hades or ASMP missiles' warheads having been dismantled, but not about the cold war citybusters...
just look at a cutview of a SCALP-EG or a MdCN, nonetheless there is payload for resp 1.8 and 1 megaton, but there's also the necessary room!! Usually, dismantlements don't happen before the actual generation is retired from active service...
Now, all that stuff is classified, but, especially considering the budget of the Strategic Force and knowing that price are way more competitive than the US ones, e.g. a B61 gravity bomb lists at about $40M... An ASMPA-R Mach3 cruise missile lists at €18M, moreover, there are no spendings for silo/land based stuff... Frankly, we're many estimating the total available between 1000 and 1200!!! To this, you add a stockpile of 30t mil-grade plutonium, enough to field 600 megatons, but the more likely is to use it as a 1st stage with 4.4kg to get a critical mass, then use much cheaper and with much better weight to yield ratio Liquid Deuterium or Lithium-6 Deuteride or Lithium-7 Deuteride for the fusion stage=> 30t is enough for 6818 first stages as the critical mass is 4.4kg, then you add the fusion fuel you need...
Then, Israel has 80 Jericho-III. Payload is enough for 3, maybe 4x 1 Megaton MIRVs... Israelis absolutely were involved at least up to the 1970 test campaign, including the highly aesthetic Licorne 1Mt test on the Mururoa atoll, as well as the 1968 2.6Mt Canopus test...
According to Colin Powell, Israel had more than 200 warheads about 1Mt while Jimmy Carter spoke about a total about 400 warheads. The Dimona reactor is the same thing as the 3 UNGG ex-reactors in Marcoule, each used to produce 100kg of Mil-grade Pu239, therefore, 400+ warheads with 240 of about 1 megaton is very realistic.
Small/medium nuke powers are more likely to do surface blasts to maximize fallouts: if a 1Mt airburst would bring serious devastation and death toll upon 500-700km² with very few fallouts, in case of surface burst it's about 20-30k km² covered with deadly fallouts and the double if not triple you need to evacuate...
Do you have ever heard a French prez bragging about the nuke arsenal? When it comes to Israel, the subject is even taboo...
Now, when it comes to the French doctrine, it includes a warning shot, a high altitude blast, in case of invasion or attack, but it also says that the an attack on the national territory will get a nuclear response... And it's commonly accepted that the national territory is... the European Union !!!! Moreover, France was the 1st to introduce stealth navy vessels, it's the 1st to introduce stealth ballistic missiles with a new form of stealth resisting even UHF radars...
I'd think twice before starting a war with a medium nuclear power, moreover, the countries tend to be smaller, the chain of command can be a lot accelerated and the much smaller conventional military may imply an over-reaction, then, the more likely is that in case of "DEFCON1", maybe even "DEFCON2", a dead-hand is very likely to be activated:
When a state-owned TV, let's say Rossiya-1, which shows what the govt. of let's say Vladolf Putler the Butcher, tells them to show, and it's such kind of threats, they may think it's funny to do so and pose as the 3ft tall bully on the block making people afraid with his baseball bat with 12 inches nails going through :
but beware of those looking like they ignore you and putting a hand in the pocket, there are 4 shots Derringers up to .357magnum and your form of "fun" may not be seen as funny but as an existential threat...
