President Donald Trump’s Iran entanglement is beginning to resemble a visual illusion known as the Penrose stairs, which endlessly climb and descend but always end up in the same place.

US forces said they hit around 90 targets across Iran on the second day of fresh attacks.

A U.S. official told Reuters that strikes targeted Iranian air defense systems, coastal surveillance systems, surface-to-air missiles, ​anti-ship cruise missiles and drone launch sites.
