A failure of Israel’s defensive weapons would require them to go on the offensive.

Yes, but it will also require them to use alternative forces on defence, and it will also induce many Israelis to leave. This will create financial and manpower shortages. This might induce even more depraved behaviour in the short term, but I guess that’s a risk Iran & Co. are willing to take to ensure long-term peace.

My understanding is that Chinese companies have been able to replicate EUV lithography by either using particle accelerators or layering DUV. But the former requires a lot of electricity, and the latter has poor quality and reliability. But with falling electricity prices and fusion reactors around the corner, who knows?

That’s normal, Mr Putin seems to be living rent-free in the heads of quite a lot of Americans and Europeans.
