Huh? There is no evidence that anyone is using a 3D printed 7.62 weapon system to do crimes. Of the existing evidence, criminals overwhelmingly use conventional firearms. I'm not understanding your point. The would-be and successful assassins in the news the last couple years used standard rifles, ranging from 5.56 to .03-06 in caliber. I think you are assuming that criminals are less sensitive to equipment reliability than they actually are.

Let me put it this way. If 3D printed firearms were such a game changer, they would already be using them at scale. They are not, and these laws are part of a fundamental misunderstanding about how firearms function and how 3D printing technology works.

Separately, I am always a little confused by the idea that you cannot "trace" these firearms. Maybe people do not widely understand what's going on here, but the serial number being traced is on this lower receiver, which can be swapped out (in most but not all cases). If a firearm with a 3D printed lower is used in a crime, I have to assume - though I am not an expert - that you could still connect spent casings to that weapon in the same manner. In other words, it does not matter that the lower doesn't have a factory-installed serial number plate or a stamped serial number. My guess is that this confusion is being injected intentionally in the debate by the people who support/push these badly constructed laws.

>You love nuclear proliferation now? You think we don't have nukes or we can't build more nukes? You think it is in the USA's best interest to have more countries with nukes everywhere? Are you dumb or do you have a death wish?

I'm talking about Intermediate Range Ballistic Missiles (IRBMs), which don't always have nuclear payloads, and which Iran, Russia, and others are desperate to produce at scale and for which Europe has no defense against without the United States. Maybe you mean that Europe would simply launch their own strategic weapons in response? Perhaps, though given the completely schizophrenic political situation there I doubt any government would approve the launch of nuclear weapons.

I'm happy to read any particular you quote you think was specifically offensive, though all I've been able to find has been something I'd book as "true, but perhaps touches a nerve with our friends across the pond". We can yell at each other back and forth but that doesn't change the reality that Europe cannot defend itself in current state without the United States, and policy makers in my country are a) acknowledging this fact and b) wanting that to change.
