President Donald Trump has said the US may consider reimposing a naval blockade on Iran in the Strait of Hormuz and possibly take over the Kharg Island, moves that could restart the war between the two countries and negatively impact the global economy.

The naval blockade was lifted last month after Iran and the US signed a Memorandum of Understanding (MoU) to end the months-long war. The war between the two countries led to a spike in global oil prices, which affected the global economy. Oil prices, which were over $100 per barrel during the war, have since dropped to around $70 per barrel since the MoU was signed.

Mr Trump also threatened a US attack on Iran tonight, stating that the Central Command will “hit Iran very hard.”

We’re going to hit them hard tonight, but we’ll see how it all works out,” Mr Trump said to reporters in Ankara, Turkey, ahead of the NATO summit.

On Tuesday night, the US military attacked Tehran in retaliation for Iranian attacks on commercial ships. According to NATO chief Mark Rutte, American strikes were “absolutely necessary”, as Iran was “basically violating the ceasefire.”
