Trump threatens 'economic warfare' against nations aiding Iran

US President Donald Trump has issued a warning that any country engaging in business or offering support to Iran will face significant economic retaliation from Washington.

In his statement, Trump used the phrase 'economic D-Day' to describe the scale and decisiveness of the potential measures being considered against nations that continue cooperating with Iran.

The warning signals an apparent strategy by the US administration to intensify pressure on Iran indirectly, by targeting third-party countries that maintain economic ties with Tehran rather than focusing solely on direct action against Iran itself. Such an approach could influence international trade decisions and prompt countries with economic links to Iran to reconsider those relationships.

The source material does not provide further details on specific measures, a timeline, or which countries might be affected by the threatened actions.
