Barrier-breaking signals

After US-Israeli strikes hit Iran's Natanz enrichment site on 21 March 2026, Iran retaliated with ballistic missiles that penetrated defenses around Dimona — Israel's nuclear research center — a first and a dangerous nuclear-threshold crossing.

On 28 February 2026 Israel and the US began a coordinated strike campaign against Iran's nuclear, missile, and regime-leadership targets — the first open, large-scale state-on-state war against Iran in the modern era.

The remains of the final hostage from the 7 October 2023 attack were returned to Israel in January 2026, formally closing the hostage chapter of the Gaza war under the October 2025 US-brokered ceasefire.

In early January 2026 the PLA conducted two days of exercises focused on Taiwan's 12-nautical-mile contiguous zone — a normalization of operations inside the buffer that US and Japan called a dangerous threshold-lowering precedent.

A US-Russia 28-point plan — including Ukrainian force caps, a NATO-accession ban and Russian sovereignty over Crimea/Donetsk/Luhansk — leaked in mid-November 2025, triggering alarm in Kyiv and Europe and reopening the war's political endgame.
