That's my sense.
I want to be supportive of Israel.
But the war Netanyahu wants to have with Iran isn't one in which I wish my country actively to participate. I'd say the same about the US. Yes, help defend Israeli air. But no, I'm not interested in invading Iran or having our armed forces lob missiles at it, in spite of thinking it is run by awful human beings.
This is Netanyahu's and hence Israel's gig. It follows on from his decision, taken on his own, to destroy Hezbollah. He's chosen to poke the hornet's nest and predictably, we are into tit-for-tat events.
