I think the thing to remember is that it doesn't really matter what 'we' think. It isn't going to change events. Possibly we could write to our politicians, or we could attend marches if we object to Israeli actions. No point protesting Hamas...they don't care. We could, of course, offer solidarity to Israeli victims, but there is always the danger that the state would read it as support for their military response. What we should do is reassure British Jews that they are welcome and safe, from us at least.
But in terms of discussion we don't have to lay down our position. It is acceptable to say 'I don't know'.
So what do we know? That Hamas are utterly amoral brutal murdering terrorists. That the Israeli response is likely to be equally cruel but in a much larger scale. That the State is casting this as an existential crisis.
What do I think will happen? I think Israel will invade Gaza and obliterate it. I think they will sink quarter of a million troops into it, and they will win but at enormous cost to themselves, civilian life, and their international position. There is the risk of this conflict spreading to Lebanon and beyond.
The US will provide support against external players such as Iran. They have warships in the region, a heavy bomber base in the UK, and abundant ELINT capability. The UK will task GCHQ to provide ELINT and Akrotiri will be very busy.
There may be very limited coverage on the ground in North Gaza City, but plenty of coverage of awful conditions in the winter refugee camps that will spring up in the south of Gaza, but very possibly in the Sinai.
One thing is certain, this is a major conflagration and it will go on for months. If we are lucky it will not spread beyond the Occupied territories, but it will kick off in the West Bank.
