Donald Trump's game of hardball with Iran is dangerous and could backfire, Prof Robert Patman warns.
Tensions with Iran have been been escalating since the United States unilaterally withdrew from the multi-party Iran Nuclear Deal and imposed economic sanctions on the Persian nation.
What the world is witnessing is not just a confrontation between the two countries, but a battle between two very different visions of how to achieve security in the Middle East, Prof Patman, an international relations specialist at the University of Otago, says.
"The Europeans and the other signatories to the Iran Nuclear Deal totally reject Mr Trump's position,'' he says.
"Mr Trump is sort of back to the future; the idea of great powers calling the shots, and hoping to bring about regime change in Iran and put in a more sympathetic regime.''
Prof Patman says it is a dangerous gamble.
"We want to encourage democratic change in that country. Mr Trump's position will probably boost the position of the hardliners in Iran.
"It's very worrying and very dangerous . . . The Americans have dispatched the Abraham Lincoln, an aircraft carrier with a strike force, plus a bomber squadron. This is a very tense area. Iran is a major player in the Middle East. I just think the prospect for miscalculation in such a situation is quite considerable.''
