All the other countries named to General Wesley Clark shortly after 9/11 have been attacked: Iraq, Lebanon, Syria, Sudan, Somalia and Lebanon.
But Iran has not.
There have been several provocations: the green revolution; sending sailors and ships into contested or Iranian waters.
But Iran has been untouched.
And there is now even a deal with Iran.
But Trump hates that deal. Here is what he told AIPAC earlier this year:
My number-one priority is to dismantle the disastrous deal with Iran...I have been in business a long time. I know deal-making. And let me tell you, this deal is catastrophic for America, for Israel and for the whole of the Middle East.
But he now seems to be shifting, or appears to be shifting:
One of Trump’s foreign policy advisers, Walid Phares, told the BBC that “ripping up is maybe a too strong of word” but that the deal would be renegotiated by the incoming administration.
...George Perkovich of the Carnegie Endowment for International Peace said Washington’s closest allies would see a unilateral bid by Washington to renegotiate as a “rogue action.”
“They would consider the United States to be in violation of the deal and would not feel bound to reimpose or tighten sanctions on Iran, as the United States might wish,” he wrote.

So it looks like Trump is going to rip up that deal. His team are calling it 'renegotiating', but as quoted above such an act would be considered a "rogue action" by the whole international community, thus destabilising the Middle East even more.
And what will Trump do if a 'renegotiation' doesn't go the way he wants?
Clue: what did he think about the actions of the Chinese government in Tiananmen Square?
