I came across a great picture online that clearly explains the differences between bayonet collars.

Honestly your best bet to stop unwanted spam and scam calls is OPSEC. Stop giving out information to third parties or use false information so they call someone else. This is one of the reasons I use an email or letter only policy for nearly every company that "needs" my personal information. With health insurance being one of the biggest breeches of personal information possible to you due to it being "federalized" on servers and constantly hacked to sell on the black market.

Blueprints aren't, but flat out giving them a nuke will come back on those that did eventually along with the consequences. China, Russia, and the Norks know exactly what they're doing and the rest of the world let them get away with it for profit margins and natural gas.

The Norks were given pretty much the same deal with Russia, Pakistan, and China. Let's be honest here too. If anyone on this board said "Here's the plans to an open bolt sub machine gun, here's my number you can call when you make it so I can walk you through it. But just make a non firing replica that still feeds but doesn't have the firing pin." we'd all agree to string them both up before they got caught robbing the local quikee mart. China, Russia, nd North Korea know damned well what they're doing and what Iran is after here.

The warhead problem is more complicated than you think also. Nuclear weapon radiation has its own fingerprint so to say. From this they can get origin as well as other vital information. Feeding the Iranians a weapon would be suicidal for any modern nation if it's used.

Yes, China has a large hand in their enrichment program.  But actual warhead development is being helped covertly by NK.  I agree, they have never stopped their nuke program, all the diplomatic efforts have been simple gas lighting since their leader stated they would never give it up and they never adhered to any of the stipulations of any of the agreements they made. And its not for energy security. That's just BS, everyone knows why they wanted higher enrichment than what is called for in a power generation reactor. But while we are cutting through the BS, any claim they were "weeks away" is just as much so.  Especially when Israel and the US have repeatedly attacked their program and claimed it was set back years, while Trump claimed "total destruction" of it just months ago.  Like I said, If China and Russia really wanted them armed with a weapon they would have had it by now, like they have conveniently "developed" hypersonic missiles all on their own that is suspiciously copies of Russian tech.

I have no problem with final confrontation with a govt that has chanted "death to America" for 40+ years, but lets not pretend this was about them imminently nuking anyone, this was about denying resources for a more intense war in the future.  And frankly I am glad someone is finally addressing that elephant on the room, even though it has been and will be even more costly, it could possibly deter a future more impactful and costly war at best, or weigh that in our favor at worst.

 The libertarian idea we can ignore away threats is more than naive, and while I dislike military adventurism, sometimes force projection is a solid defense strategy in a world where there are no perfect solutions to actual threats.
