The United States is set to begin a blockade of Iranian ports at 10:00 ET on Monday, following unsuccessful diplomatic discussions in Islamabad. The US military clarified that it will not obstruct vessels traveling to or from other countries, but tensions remain high as Iran has vowed to respond severely to any military presence in the Strait of Hormuz. Oil prices have surged above $100 amid these developments. This shift in strategy appears to be a response to the failure of talks and the recent lifting of sanctions on Iranian oil shipments, which had allowed Iran to finance its military efforts. Experts suggest that the blockade could leave Iran with limited options, potentially impacting the flow of oil through this critical maritime route. Trump's recent comments about a joint venture with Iran to manage the Strait contrast sharply with the US's historical commitment to free navigation. This reflects a broader trend in Trump's foreign policy, viewing international relations through a transactional lens rather than as a commitment to shared global values.
