In the wake of the upcoming U.S. presidential election, Iran is apprehensive about the potential return of Donald Trump to power.

Polls indicate a tight race between Republican Donald Trump and Democratic Vice President Kamala Harris.

However, the Iranian leadership and its allies in Lebanon, Iraq, and Yemen fear Trump's return could lead to increased tensions.

They are concerned that Trump might enable Israeli Prime Minister Benjamin Netanyahu to strike Iranian nuclear sites, execute targeted assassinations, and reinstate the 'maximum pressure policy' by intensifying sanctions on Iran's oil sector.

Analysts suggest this would severely impact Iran's economic and foreign policy stance and possibly force Iran to negotiate a tougher nuclear deal.

The prospect of a U.S.-Saudi defense pact, with Riyadh initiating diplomatic relations with Israel, further poses a challenge to Iran and Supreme Leader Ayatollah Ali Khamenei.

Middle Eastern stability could be shifted if a new coalition against Iran emerges.

Trump had previously withdrawn from the 2015 nuclear deal, ordered the killing of a key Iranian general, and applied stringent sanctions which worsened Iran's economic situation.

His potential return is viewed as more detrimental due to his firm backing of Israel, positioning Iran in a precarious situation within the regional power play.

Despite harsh rhetoric, Iran might have to consider a renegotiated nuclear agreement suited to Trump's vision.
