"America's withdrawal from the nuclear deal is a clear proof America can not be trusted".
U.S. President Donald Trump last week reimposed a set of sanctions that had been lifted as part of the 2015 nuclear deal Iran struck with world powers to limit the country's nuclear program in exchange for relief from measures that had badly hurt its economy.

Khamenei went on to rule out the possibility of armed conflict with the United States, saying that "war will not happen", according to the AP.

Thousands of Iranians have protested in recent weeks against sharp rises in the prices of some food items, a lack of jobs and state corruption. "I do not call it betrayal but a huge mistake in management", state TV quoted Khamenei as saying.
Khamenei said Monday that the monetary crisis resulted from "management problems unrelated to sanctions" and blamed the administration of Iranian President Hassan Rouhani, the news service added.
The rial has lost about half of its value since April in anticipation of the renewed USA sanctions. The protests over the cost of living have often turned into anti-government rallies.
"The corrupt people [officials] should be punished firmly", Khamenei said on Monday.
Meanwhile, Iran on Monday unveiled a next generation short-range ballistic missile.
