The last line is exactly it. Trump wants to destabilize American society and the American economy so he can claim emergency presidential powers and then never give up the presidency since he will ensure we are in a constant state of emergency. The same way the Roman emperors were given power by the Senate and then just kept that power. Trump envisions doing exactly the same. There will be no need to change the Constitution to allow him to run for a third term, he will just abolish the vote in the name of national security.A mate of mines wife and kids are over in Europe, he's worried about how they fly back.
God knows where Iran will strike? Its likely going to be a terror attack of some sort, the question is where and how and against who? US? UK? God knows.
If Iran manages an attack on US soil it will give Trump a pretext to suspend a heap more freedoms.
