Foreign secretary denounces 'reckless Iran threats' after missiles fired at Diego Garcia

Iran reportedly fired two ballistic missiles at Indian Ocean base, but neither reached the target.

Unfortunately this is more interesting than a failed Diego Garcia attack — the late Ayatollah had a self-imposed range limit on the strikes or tests they would carry out. By using IRBMs in this fashion, it’s clear the new regime no longer feels bound by that restriction..

Which is notable since it’s about the same distance from Southern Iran to Diego Garcia (3,800km) as it is from Northern Iran to London.

I'd add that it's also a free opportunity to test IRBM targeting at much longer ranges.

The war of choice is really the US's Teutoburg Forest moment.
