• Tehran’s approach speaks cautiously, keeps wary of Trump’s deal.
• Although we believe it, it is supported by leaders.
• Iran, the United States holds active talks in Oman; expected on April 19.

Supreme leader Ayatollah Ali Khamenei said on Tuesday that he was neither “overly optimistic nor pessimistic” about his talks with the United States on Iran’s nuclear program, apparently a move by Tehran to make increasingly public expectations for a deal.

Iranian politicians and insiders say the failure to reach a deal with President Donald Trump to end the decades-long dispute between Iran and the West could seriously harm the Islamic Republic, even if Washington was subsequently portrayed by Tehran as a guilty party.

Expectations for economic relief soared after negotiations in Oman in Tehran and Washington last weekend in Oman, according to news posted by Iranians over the phone and on social media.

The two sides agreed to hold more talks in Oman on April 19.

Iran’s abused riyal currency has risen about 20% against the dollar over the past few days, and many Iranians hope to reach a deal to end Iran’s economic quarantine.

“We are neither overly optimistic nor pessimistic about them. After all, it is a decision process and its first step has been well implemented,” Khamenei said in a meeting with lawmakers.

Tehran held talks cautiously, doubting the possibility of a deal and doubts Trump’s 2015 nuclear deal in his first term in 2018, abandoned six powers in his first term in 2018, and repeatedly threatened to bomb Iran without a deal.

“From here on, it’s necessary to follow carefully (negotiation), and the red line is clearly defined for the other end and for us. Negotiation may lead to results, or may not,” Khamenei said.

“Avoid connecting the fate of the country to these conversations.”

Since relations with Washington collapsed, Iran removed the Islamic revolution of the United States-backed Shah in 1979, and hatred of the United States has been a rally for the rulers of Iranian instruments.

But after Trump abandoned the 2015 nuclear deal, inflation, unemployment and lack of investment due to severe sanctions and persuaded Khamenei to support talks with the Trump administration.
