Press TV - US President Donald Trump�s hostile comments against the Iranian nation during his speech at the UN General Assembly on Tuesday were lies that underscored the US leader�s �ignorance� about the Islamic Republic, says an American political analyst.

Trump�s accusations against Iran �really shows an ignorance of facts and ignorance of history,� said Scott Bennett, a former US military psychological warfare officer.

�The president was speaking the same lies and corrupt half-truths that his people [aides] have told him and it very sad because he is dangerously positioning the United States with a confict against Russia and Iran,� Bennett told Press TV on Wednesday.

Trump launched a scathing attack against Iran on Tuesday at his speech to the UN General Assembly, accusing Tehran of sowing "chaos, death and destruction"�across the Middle East.

He also alleged once again that Iran was �the world�s leading sponsor of terrorism� and promised hard-hitting sanctions against Tehran while urging the world to isolate the Islamic Republic.

On Wednesday, Trump chaired the UN Security Council meeting which focused on the non-proliferation of weapons of mass destruction.

During the Security Council meeting, Trump�threatened that any individuals or entities that fail to comply with Iran sanctions will �face server consequences� and stressed that the US will ensure Iran will never get a nuclear bomb.

He also said that the US will pursue tougher Iran sanctions, �tougher than ever before,� and defended re-imposing sanctions on Iran, citing its "malign conduct."

Trump withdrew from the 2015 nuclear deal that Iran signed with six world powers, including the US.

Also speaking at the meeting was French President Emmanuel Macron who said that sanctions and containment were not solutions to the Iranian issue.

He said that Iran has lived up to its commitments under the 2015 nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA), and so should other signatories to the deal.

British Prime Minister Theresa May also defended the JCPOA as an �important� achievement, and stressed that her country will be committed to preserving the agreement as long as Iran lives up to its commitments.
