Extended naval blockade is an admission US military escalation poses even greater risk

Battle of the blockades may still have more time to run as both the US and Iran try to assert control over the strait of Hormuz

Donald Trump’s decision to extend the naval blockade of Iran indefinitely may do nothing to reduce world oil prices – but it could amount to a recognition that further US military escalation in breach of the nominal ceasefire comes with greater risk against a regime disinclined to surrender.

In theory, Trump’s military options are increasing. A third US carrier strike group, the George HW Bush, is due to arrive in the Middle East within days after rounding South Africa. A second taskforce of 2,500 US marines is sailing from the Pacific and is due to arrive by the end of April.
