Washington DC: US President Donald Trump on Monday (September 14) vowed that any attack by Iran would be met with a response "1,000 times greater in magnitude," after reports that Iran planned to avenge the killing of top general Qasem Soleimani in January.

"According to press reports, Iran may be planning an assassination, or other attack, against the United States in retaliation for the killing of terrorist leader Soleimani, which was carried out for his planning a future attack, murdering U.S. Troops, and the death & suffering...caused over so many years. Any attack by Iran, in any form, against the United States will be met with an attack on Iran that will be 1,000 times greater in magnitude!" Trump tweeted after reports of an alleged Iranian plot to assassinate the US ambassador to South Africa.

However, senior Democrats cautioned Trump against attacking Iran without consulting Congress, a step he chose to forgo before the January killing of a top Iranian commander that pushed the countries to the brink of war. In a letter on March 27, Democratic leaders wrote that Trump must discuss with lawmakers any potential military actions overseas and noted that recent attacks on American forces in Iraq highlighted threats that could require a military response.

On January 2 of this year, US Troops used an air strike to kill the leader of Iranian Forces, Qassim Suleimani. At the time, the Pentagon said Suleimani and his force were planning an attack on US troops in the regions.

The drone strike took place at Baghdad International Airport. It was authorized by Trump. The attack on the Iranian militia architect was an act of vengeance by the US following the December rocket attack of an Iraqi military base that killed American soldiers and a contractor.

Iran's Supreme Leader Ali Khamenei described the missile attacks as a "slap in the face" for the US and called for an end to the American presence in the Middle East.
