With 2025 marking 80 years since the atomic bombings of Hiroshima and Nagasaki, UNIDIR continues its work to reduce nuclear risks through research and dialogue. #UNIDIR45 The Nuclear Non-Proliferation Treaty remains central to this work. Do you know when it entered into force?

Yes, of course. It's called "initial declaration." Having an agreement with verification provisions can get you a lot of interesting information.

Wow. Trump intends to meet with Putin directly as soon as next week and then, “shortly afterward,” hold a trilateral meeting with Zelensky too. “It was not immediately clear if Mr. Putin or Mr. Zelensky had agreed to the plan Mr. Trump described.” lol nytimes.com/2025/08/06/us/…

This is brilliant...

The source is, how should I say it?, not exactly reliable. Here is the lecture given by Boris Litvinov (Chief Designer of the Chelyabinsk/Snezhinsk KB) in 2001: elib.biblioatom.ru/text/litvinov_… He doesn't give a specific number, but there is no way 1.5 m is a critical height for a weapon

Wait, there was a 9M728 container at the 2019 event?

"Ukrainian Support for War Effort Collapses" -- quite a headline for the new Gallup poll. Somewhat of an exaggeration of the actual findings, but nonetheless there is a strong shift toward support for negotiating an end to the war in the short term. news.gallup.com/poll/693203/uk…

So the deal, according to Bloomberg, is all of Donetsk and Lugansk regions to Ru in exchange for a Russian promise not to advance to Kherson and Zaporizhia and a full freeze. Plus some kind of a US/Ru memo on future relations between Ru and the West, plus some sanctions relief.

Pete Hegseth doesn’t want to talk about his hugely ambitious missile defense project. Maybe that’s because all anyone knows about Golden Dome is that it will be an expensive, all-azimuth defense against everything that flies - and unlikely to work theatlantic.com/national-secur…
