Looks like Ribbentrop and Molotov just gave each other a follow on Twitter.

They finally made an economist with public speaking skills and they immediately started putting up Assad numbers
Mark Carney’s approval hit 70%, the highest level, surpassing Chrétien’s 66%. So freaking awesome.

Bukayo Saka’s hat trick should see Thomas Tuchel’s resignation. That he played no part against Argentina is shocking.

Given the volume of fraudulent documents bearing that signature, probably time for Euros.
GREG KELLY: Your signature is on a legal piece of currency. What does it mean to you? TRUMP: It's always an honor to have your name on something like that, and it's on all the currency. It's great. They also just came out with a silver dollar, which is very nice. I don't fight them, believe it or not.

In Germany, a talented 14-year-old earns his club money. In America, his parents pay the club $15,000 a year. That single inversion explains why "we will not" is the most accurate line ever written about US soccer. FIFA built a global system for this. Training compensation and solidarity payments send a cut of every transfer fee back to the clubs that developed the player, from age 12 onward. Develop one future pro and your academy gets paid for a decade. Barcelona's La Masia, Ajax, every Bundesliga academy runs on this logic. The kid is the asset. US Soccer refuses to enforce those rules. When Seattle's Crossfire Premier claimed its $60,000 share of DeAndre Yedlin's transfer to Tottenham, it got nothing. Claims on the Dempsey and Bradley transfers died partly because the federation couldn't even produce the youth training records. So American clubs earn zero dollars when a kid turns pro. They earn when a kid enrolls. Which makes the parent the customer, and the product is whatever keeps the parent writing checks: travel tournaments, hotel weekends, $500 showcase events, private training at $100 an hour. Elite pathways run $8,000 to $20,000 a year. A comparable academy spot in Italy costs about 120 euros. Follow the incentive one level deeper and it gets darker. A club dependent on fees can't cut its weakest paying players, so rosters optimize for retention over development. The scouting pool shrinks to families who can afford the cliff, which appears around age 11, exactly when development matters most. The country runs a talent filter sorted by household income instead of ability. Every four years someone proposes fixing this. The proposal always requires the people profiting from the $15,000 model to vote themselves out of business. They will not.
“And every four years when the World Cup comes around, we will say that we’d dominate if we had a stronger youth program.” “And will we develop a stronger youth program?” “We will not.”

Extracting a probability from a doctor is one of life's unnecessary boss battles. Even if you beg them for an interval-valued subjective probability, and at that point you're basically asking for their hunch. I don't know if they get sued for giving out information or something.

Argentina advance after a rare successful encounter with a small Atlantic island.
From one small Atlantic island to another: good luck Cape Verde. Purely island solidarity, obviously. 🇫🇰🇨🇻

Jose Mourinho never disappoints.
🚨🗣️ José Mourinho on the VAR double standard between Lionel Messi and Folarin Balogun: "When I speak about the system, people call me crazy. They say Mourinho is always complaining. But today, the whole world saw the script with their own eyes. Folarin Balogun makes an accidental step, a completely natural movement of a striker fighting for the ball, and VAR calls the referee like a crime has been committed. A straight red card. He misses the biggest game of his life. But when the poster boy of FIFA, Lionel Messi, puts his studs into the calf of an opponent, the VAR room suddenly loses their internet connection. The referee goes blind. It is a completely different rulebook. If Balogun's name was Folarin Messi, he would not have even received a warning. It is not about the severity of the foul anymore; it is entirely about the name printed on the back of the shirt. It is a disgrace."
