As correctly quoted in the TFA main point of this project is to make up for the bad strategic choices that Europe made 10-15 years ago on that topic (and believe me, Europe made bad strategic choices in the past 10-15 years on a LOT of topics).

So this may seem stupid, but if Europe doesn't make the move, when Donald Trump Jr is elected in 2032 and decides to bar the EU from space, what will Europe do?
Don't see this project as a copycat of Musk, see it as a seek to preserve independent access to space.... Oh, and about the efficiency of ArianeGroup, please remember that it's a subsidiary of Airbus that seems to perform a bit better that Boeing in the past years...

Actually that's way more complex, and the greens behind this know it first hand, as they are mainly responsible for the situation. So what happened ?
- emissions in 1990 were already very low, because most electricity was already coming from nukes then
- deployment of so-called "renewable" energy sources in the 2000's-2010's actually lead to the building of new gas-powered plants, because renewable energies function approx 25% of the time (no sun at night, no wind very often in summer, etc.). so this actually increased the greenhouse gas emissions
- finally, under pressure from the greens, they started to close nuclear power plants. One of them, Fessenheim, is fully closed already

Another post pointed also at the failure due to increased smog and particles pollution. While this is true, it is in a great part not due to the French. The nearby Germany stopped using nuclear power plants at all, and reverted to coal power plants. This resulted in s spectacular increase of smog and particles emission, which happen to have no border. As a result, last year, in March, during the first full lockdown when no cars at all were on the streets and what is left of the French industry was completely stopped, a particle pollution peak was registered.

Don't get fooled by NGOs such as Oxfam... They have a political agenda, and it's not the one you think at first glance...

What you're describing is a Lumia with Windows 10 for phones, managed by Intune.

And no, it's not what businesses want. Intune/SCCM is full of proprietary stuff, that doesn't stick to the diversity of a modern information system.

There are two: the RAID (police forces) and the GIGN (gendarmerie - the army).

And yes they are involved at least in one of the ongoing attacks (the Bataclan concert hall).
