And once the chip fabs have been bombed, civilisation is set by by decades, and may end up fighting a lower-tech war.
Beyond this, if you start attacking neutral fabs you lose out on anything from them. Your expectations are quite a bit off if you think striking fabs stops a conflict.

Had "EU" wanted to hurt Russia there were was a thousand ways to do that. But they didn't. Instead they traded and built infrastructure. Most EU countries saw Russia as a partner before they invaded their neighbour in the most gruesome way possible.
If anything, the EU should have reacted sooner. It was shameful they didn't. You can't really pretend like nothing while an all out war is taking place on the same continent.
By WHO?! Russia is still stuck in 1/4 of the Ukraine and fear mongers make it sound like they're about to reach Paris any day now.
