First, NATO and Kiev signed a letter of intent in February for cooperation between their special operations forces. Two months later American ambassador and current NATO Deputy Secretary-General Alexander Vershbow said it was time to bring the Ukrainian military “in line with NATO standards.” Barely one week later, though, the U.S. Ambassador to NATO ruled out NATO expansion for the “next several years.”

These muddled messages only cause confusion, provoking Russia while potentially false hope for Ukraine. For that reason, it’s time for Washington to make clear that Ukrainian accession to NATO is not on the table. Here’s why.

First, NATO possesses almost no ability to defend Ukraine. Russia has 270,000 troops and 700 jet fighters positioned on Ukraine’s southern and western borders. And as Russia demonstrated in 2015 when it sent 150,000 troops to surround Ukraine, Moscow can quickly mobilize its military in the event of a conflict.

Yelp gets horrible reviews from investors and potential employees


Investors gave Yelp Inc. some pretty awful reviews after a second quarter full of unpleasant surprises, and some may now be wondering if its long-term goal to reach $1 billion in revenue is a pipe dream as the company has trouble attracting employees.

Yelp’s YELP, -0.65%  shares fell more than 16% in after-hours trading on Tuesday, after providing a disappointing outlook for the rest of the year. The review site told investors that it was shutting down its display advertising business by the end of the year, not hiring as many sales people as it had originally projected, and its revenue would take a hit as a result of both moves. Yelp lowered its guidance for full-year revenue to a range of $544 million to $550 million, from a previous range of $574 million to $579 million.
