And demonstrating just how prescient Carter is:

Israel and the United States will soon be destroyed, Iran’s President Mahmoud Ahmadinejad said Tuesday during a meeting with Syria’s foreign minister, the Islamic Republic of Iran Broadcasting (IRIB) website said in a report.
“Iranian President Mahmoud Ahmadinejad… assured that the United States and the Zionist regime of Israel will soon come to the end of their lives,” the Iranian president was quoted as saying.
“Sparking discord among Muslims, especially between the Shiites and Sunnis, is a plot hatched by the Zionists and the US for dominating regional nations and looting their resources,” Ahmadinejad added, according to the report.
The Iranian president also directly tied events in Lebanon to a wider plan aimed at Israel’s destruction. He called on “regional countries” to “support the Islamic resistance of the Lebanese people and strive to enhance solidarity and unity among the different Palestinian groups in a bid to pave the ground for the undermining of the Zionist regime whose demise is, of course, imminent.”

A man who is actively seeking to acquire nuclear weapons is bent on our destruction but according to Carter we have nothing to fear.
