US Democratic Presidential candidate Joe Biden has blasted President Donald Trump’s tweets on Iran as incredibly dangerous and irresponsible after Trump threatened to strike 52 important targets in Iran, including the cultural ones.

On Saturday, Trump said on Twitter that his military would hit very important targets related to Iran if the Iranians attempted to take retaliatory action against the US for the assassination of Lieutenant General Qassem Soleimani. The Pentagon said Trump had ordered Soleimani’s assassination.

When he makes statements like that, it just seems to me to be he’s going off on a tweet storm on his own, and it’s incredibly dangerous and irresponsible, Biden told reporters.

I have no idea whether he’s coordinated with any of our allies. I have no idea whether or not he has the support of his own generals, the former vice president added. This is a guy who seems to be unmoored.

Reacting to Trump’s tweet later on Sunday, Iran’s Foreign Minister Mohammad Javad Zarif also took to his official Twitter account reminding Trump that although barbarians have come and ravaged our cities, razed our monuments and burnt our libraries throughout history, Iranians still stand tall.

Zarif also drew an analogy between Trump’s assertions and Daesh’s crimes in destroying cultural heritage of some regional countries, noting that the US president is hallucinating about emulating ISIS war crimes by targeting our cultural heritage.

Soleimani, the commander of the Quds Force of Iran’s Islamic Revolution Guards Corps (IRGC), and Abu Mahdi al-Muhandis, the second-in-command of Iraq’s Popular Mobilization Units (PMU), were assassinated in US airstrikes in the Iraqi capital Baghdad on Friday.

Trump’s threats came after Iranian authorities said they would show a harsh response to the US strikes.

In his new tweets, Trump said that the US would use brand new beautiful equipment to hit the Islamic Republic without hesitation.

Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei promised severe revenge for the death of the military commander. Ayatollah Khamenei said the cruelest people on earth assassinated the honorable commander who courageously fought for years against the evils and bandits of the world.

Trump has claimed he authorized the assassination of the commander of the Quds Force in Iraq to stop a war, but his Democratic presidential contenders have said that his action has put the United States on a warpath.
