It was clear that the Zionist regime of Israel and some countries like Saudi Arabia have played a major role in writing Trump's speech and guiding him, Larijani was quoted as saying on Sunday by Press TV, Xinhua reported.
Trump's aggressive rhetoric was aimed to cause commotion and prevent international economic cooperation with Iran, he added.
On Friday, the US President refused to certify Iran's international nuclear deal and accused Tehran of sponsoring terrorism, saying that he would deny Iran's "all paths to a nuclear weapon".
Iran has insisted that its nuclear energy programme is aimed at civilian purposes.
