Iran’s Foreign Ministry spokesman Abbas Mousavi has addressed United States officials in a tweet, saying that Washington was facing a choice of either admitting defeat and beginning to show respect for the Iranian nation, or “further humiliating itself”.

​The tweet makes mention of the US maximum pressure campaign on Iran, vowing to respond to it with “maximum resistance, stiffening resolve and reliance on the national capabilities”.

The tweeted remarks were in response to recent comments, made by US Special Representative for Iran Brian Hook, who claimed US President Donald Trump’s “maximum pressure” policy was offering Iran the options of either negotiating with Washington or dealing with what he assessed as “economic collapse” as fallout from US sanctions.

During a conference call at a State Department special briefing last week, Hook said:

“Because of our pressure, Iran’s leaders are facing a decision: Either negotiate with us or manage economic collapse.”

Earlier on Wednesday, US Secretary of State Mike Pompeo announced that Washington was ending the last remaining sanctions waivers in the Joint Comprehensive Plan of Action (JCPOA), saying that Iran’s alleged “nuclear brinkmanship” in breaching some of its nuclear commitments did not justify renewing the waivers.
