The sanctions and ripping up the Iran deal came before the embassy was attacked. The point he is making is that these are simply predictable reactions..
We’re aware that the sanctions and ending the Iran deal had already happened.
What do you mean ‘these are predictable reactions” ?
Obama and Iran KNEW that the "Iran deal" wasn't worth the paper it was written on, since the senate never voted on it. And President Trump said he would void the deal when he became President.
If Obama wanted a legitimate deal, he should have submitted it to the senate for a vote, and lobbied for the senate to pass it. Instead, he did what lefties always do... He took a short-cut, an end-run around the Constitution, which is what he called "a document of 'negative rights.'"
