It matters less than before. The US is no longer the dominant force it used to be in the 1950s, and the UK (which was part of the anti-Mossadegh plot) is completely gone from the world stage.

The world of 2026 cannot be reduced to a CIA/Mossad theatre where everyone else is a NPC and must suffer whatever they cook up there. Other people have agency and do their things. EU, India, China, Iran, Russia, Qatar, all influential players.
