Call me a conspiracy theorist if you like, but why would Lebanese Hesbollah fire a Shahed drone at the British airbase at Akrotiri when they could have sent it in Israel's direction? Similarly, if Iran wanted to involve us, why not just send a drone in the direction of a British embassy or consulate in the Persian Gulf?
Have worked in defence research 15 years ago, I have a very rough idea of what the detection and tracking capabilities might be, and the Americans are probably tracking everything larger than a mosquito. On that basis, until I see reasonable evidence of exactly where it was launched from, I'm not going to rule out the possibility that our Israeli "friends" fired it, in order to try to get us involved.
