“Trump on Friday angrily accused Iran of violating”

Not the agreement, the spirit of the agreement.

In other words, Iran hasn't violated the agreement, so those intent on attacking the country are once more trying to move the goalposts. Just as they did through this agreement. Sad to see the mass media once more playing along, the folly of allowing those who profit from conflict not only to determine policy, but own the media as well.

The intelligence community, US and Israeli agencies included, along with the UN, say Iran is in compliance. 

“the omission of provisions on ballistic missile testing and terrorism”

Those things are completely irrelevant to this agreement.

“the deal — which he has called the worst in U.S. history”

Dutifully reading the script drafted by Israel’s far-right.

"he has twice reluctantly certified that Iran is fulfilling its commitments”

There was nothing else he really could do, as this was simply the truth.
