Iran Accuses US of Violating Peace Memorandum and UN Charter; Monday Asia Open the Binding Pivot

Iran’s Saturday formal charge that the US violated the Lake Lucerne memorandum and the UN Charter holds through Sunday evening, heightening tensions following the Friday cargo-ship escalation.

The Saudi-led six-state regional alignment continues backing framework architecture.
