Today's edition of quick hits:
* Keep expectations low: "Greece and its European creditors began talking again on Tuesday about how to keep Greece afloat financially, but appeared not to be moving fast enough to prevent the country from missing a debt payment due at the end of the day."
* Iran: "Pushing past a Tuesday deadline, world powers and Iran extended negotiations for a comprehensive nuclear agreement by a week as the U.N. nuclear agency prepared to announce Tehran had met a key condition -- significantly reducing its stocks of enriched uranium that could be used for atomic weapons."
* Climate policy: "In a jam-packed but complex day for international climate action, Brazil, the United States, and China -- three of the world's top 10 greenhouse gas emitters -- all announced new goals Tuesday. The commitments came in different forms and units, ranging from forest hectares to renewable energy gigawatts -- but collectively appeared to represent a new and major step forward towards addressing climate change and cleaning global energy systems."
* This is likely to be a huge case: "The Supreme Court on Tuesday agreed to hear a challenge to the way public-sector unions finance their operations. Union officials said a ruling against them would deal a blow to organized labor."
* A great week, but not the greatest week: "President Barack Obama said Tuesday that last week -- when he won historic victories on trade, health care and gay rights -- was "gratifying," but he stopped short of calling it his "best week ever," as some pundits have."
* I suppose this is how the system is supposed to work: "A county clerk in Arkansas intends to resign from her position because she doesn't believe in issuing marriage licenses to same-sex couples." If you don't want to issue marriage licenses, it's probably best that you don't keep a job that requires you to issue marriage licenses.
* In related news: "Gay couples can now seek marriage licenses in every state in the country, thanks to the recent Supreme Court decision, but that doesn't mean they'll get a warm welcome. A woman waiting in line in the clerk's office in Sioux Falls, South Dakota -- one of the states where same-sex marriage wasn't legal until Friday's ruling -- says she overheard the clerk comparing gay marriage to bestiality."
* Someone really should tell this guy to stop talking: "Michael Oren -- who was Israel's ambassador to the US until 2013, and is now a member of Israel's legislature and the author of a new book on the US-Israel alliance -- has been spending a lot of his book tour promoting a very strange idea. President Obama's Middle East policy, Oren says, is really a product of two personal links to Islam: his Kenyan father and his Indonesian stepfather."
* Well said: "Briefly put, [King v. Burwell] was one of the great trolling exercises in the history of American health policy. Thank goodness it has been resolved. Good riddance to it."
