Donald Trump denounced the New START Treaty in his first phonecall with Vladimir Putin. Putin brought up the treaty, which is coming up for renewal in 2021, so talks should be starting soon. The treaty limits the numbers of nuclear weapons for Russia and the United States, preventing an arms race. But the treaty was negotiated under Barack Obama, so in Trump’s mind, it is a bad treaty.

Sorry to be depressing, but we need to be aware of how we can lose our democracy, given many of the things that Donald Trump and his administration-to-be have said and done. It’s not an overnight change, but one little thing after another. The best thing is to avoid getting into those little things.

Back in April, the Obama administration decided to defund the plant intended to produce mixed uranium-plutonium oxide nuclear reactor fuel (MOX) out of plutonium recovered from decommissioned nuclear weapons. This was part of an agreement struck with Russia in the 1990s to dispose of 34 tons of weapons plutonium. My read in April, and Pavel Podvig’s. Read More

On April 26, it will be thirty years since the Chernobyl reactor blew up.

Here’s a good history of the Chernobyl event. Photo from here of the containment now being built for the ruined reactor. Read More
Everything you need to know about gravitational waves. Supposedly a bit announcement coming on Thursday. Graphic from here: gravity waves from two black holes orbiting around each other. Read More
Alexei Arbatov considers the possibilities of nuclear war between Russia and the United States. It sounds like Putin’s “strike first” comment made Arbatov wonder if Putin intended that for nuclear war. He decides not, but, I think, not entirely convincingly. This is one of the issues the United States and Russia need to talk about. Read More
Did Iran give up the Khobar Towers terrorist? Apparently yes; perhaps a sign that relations can improve after the nuclear agreement. Also, first American students accepted at an Iranian university.
