The (bad CGI) video that Turkiye released shows the 6,000 km #yildirimhan ICBM striking what looks like Diego Garcia and the Eastern Seaboard. https://t.co/HOvEE1QIvf

Putin’s AI Advisor: Virtual Andropov Replaces Human Counsel

Dark Eagle Extends Moscow Reach via Middle East

An interesting wrinkle to @mgerrydoyle's story is that Dark Eagle can also range Moscow from Israel, Jordan and the Gulf. https://t.co/MgOn1Ht6oI

Sticking to JCPOA Wouldn't Have Prevented Iran's Breakout

For what its worth, if the US had stuck with the JCPOA and we spot him his convenient counterfactual -- Iran breaks out anyway -- we'd have exactly the same recourse we're taking now, i.e. the total fiasco of...

Dear @CPTArmageddon. @dex_eve and I *discovered* the first ~120 Chinese DF-31 silos, not belittled their existence. Whatever personal animosity you have against me or my policy views, facts are facts. https://t.co/TTJCDGDrda

Iran Cut JCPOA Compliance Right After Trump, Not Ignored

The people cheerleading this war are now pretending that Iran never dared walk away from JCPOA commitments under Trump. The problem is that Iran immediately and publicly began limiting its compliance as many of us noted at the time. 👇

Trump’s JCPOA Exit Let Iran Build HEU Stockpile

Iran did not have a stockpile of highly enriched uranium until after Trump withdrew from the JCPOA because Iran was prohibited from doing so and under monitoring, Trump is the arsonist taking credit for putting out the fire he started.

Iran's Actions Reveal Trust Deficit, Not Broken Promises

Iran made the same statement when it acceded to the NPT, when Khamenei issued the beaten-to-death fatwa and when Zarif signed the JCPOA. We lacked trust, not promises.

Strike Missile Likely PrSM, Not Iranian Cruise Missile

I told @trbtc & @johnismay (@nytimes) the missile involved in the strike that killed 21 civilians, including at least 5 children, appears to be ~15 feet long--closer to a PrSM than an Iranian cruise missile. This is how...

Trump Shouldn't Order Navy to Sink Chinese Warship
