The closest conflicts I have seen is varying codes required and there is usually clear language to use the strictest code. For example one code might require piping with 1/8” thickness if it holds water at X pressure and another will requires 3/16” thickness if that water is going to have a chloride content above X amount so you if it meets both you use the 3/16”.

Except Germany is in a formal treaty with France and the UK who both have nuclear weapons

If someone attacks Germany’s nuclear power plants the world as we know it won’t exist because nuclear weapons will launch ravaging most of the world.

Also you don’t need to attack every single solar panel, just the power distribution centers

You can’t legally consent to things if you aren’t of sound mind and body.
