I would suggest HARM Missiles launched from F/A 18 Aircraft. That will teach the effing russians to mess with GPS

I prefer homemade anyways.

Every time I look at the demo devices in a shop like media market or Saturn selling foldables, the screens of most devices are damaged. There are always cracks, discolorations or some kind of screen damage to these devices. If brand new demo pieces can't last a few weeks, why would I bother to buy one, knowing it won't last the usual 3 years of smartphone use?

If we count in rubles there's probably gazillions.

Sorry, this is not correct. France is importing massive amounts of electricity power from renewable sources from Germany, because the France nuclear power plants are out of order, without cooling water or have cracks in the containment.
