It was quite common to see Quakers and Methodists at the gate as the site emptied in the evenings, usually they were just handing out leaflets and chatting while the traffic lights changed. While you might be sympathetic to their moral stance, I strongly suspect their basic premise is incorrect; is the Saudi Typhoon being used against Yemen?
Disputes in this area date back at least to the early 70s (Lightnings in ops with RAF secondee aircrew) and I believe the current flare up was initiated by the Yemenis' armed incursions across the border a few years ago. Since the initial skirmishes the Iranians have ratcheted up their involvement and support to the Yemenis as part of their geopolitical moves against the Saudis. This is far from the simple conflict depicted by our press.
