How Iran could respond to US bomb strikes that would affect the entire world

A video has been circulating, suggesting a measure that Iran could take following bomb strikes from the US.

Last night (21 June), President Donald Trump ordered US forces to strike Iran amid the Middle Eastern nation's growing tensions with Israel.

In the weeks preceding the attack, Iran and Israel exchanged missiles, with the former calling the attacks a 'declaration of war', in a statement that had millions around the world worried.

But now, the US have got involved in the conflict at Israel's defence, as Trump and his team decided over the course of 48 hours to launch an attack on Iran, amid whispers that they were developing nuclear weapons.

A fleet of technologically advanced B-2 stealth bombers were used to drop 12 warheads on Iran's primary nuclear facility, located in Fordow, while submarines were used to fire 30 Tomahawk missiles at two other targeted Iranian bases in Natanz and Esfahan.

All eyes are now on Iran, who look like they could be on the brink of doing something drastic, which could affect several nations across the world.

Reports from Iranian media suggest that the government have green-lit the closure of the Strait of Hormuz, a 21-mile strait between the Persian Gulf and the Gulf of Oman.

The importance of this body of water can't be emphasised enough, as Iran's Supreme National Security Council, headed up by Supreme Leader Ali Khamenei, is now considering if they should close it off completely, according to Al Arabiya.

It's a key point for nations around the world when it comes to energy supplies, given that nearly half of the world's proven oil reserves are in the Middle East, specifically in Saudi Arabia and Iran.

The narrow passage connects the Persian Gulf and the Arabian Sea, and it is considered to be one of the most critical maritime routes when it comes to global energy transit.

20 percent of the world's oil and natural gas supplies pass through this strait, and any disruption to these ships, even if temporary, could have catastrophic effects on global energy markets.

People are now bracing for a spike in oil prices and a drop in the economy, if Iran was to close the strait.

The nation has threatened to do so in the past, while tension with the US was also high, though it looks like it could go through this time.

Reports have suggested that the Iranian parliament has approved the decision, awaiting the final go-ahead.

The consequences would reverberate across the world, with markets in danger of a sharp drop, and while a temporary closure would be detrimental to several countries, a permanent one has the potential to destabilise several nations.

It is not currently clear on how close Iran is to approving the measure, or if it is simply a bargaining chip as tensions with the US reach an all-time high.
