Trump's ultimatum on Iran deal out of touch with reality

Though Donald Trump did heed appeals from advisers and allies and waive sanctions against Iran, he simultaneously planted a time bomb for the Iran nuclear deal, the United States' relations with its allies, as well as peace and stability in the Middle East.

Warning that the waiver was "the last chance" to "fix the terrible flaws" in the agreement, he threatened to withdraw the US "immediately" otherwise.

Such a blunt ultimatum, as has been typical of his unilateralist approach to significant international affairs, is both irresponsible and potentially dangerous.
