To be honest, Israel is very very aggressive in terms of warfare and they’re only doing it so that they take more land... On the other hand the UK is just a puppet of USA... and this is coming from someone who lives in UK
Our politicians don't have the backbone to stand up to the US and the ones that might are obliterated by the press (not a Corbyn fan but it's interesting to read what the press says and then what he actually said just to see how blatant it is).
Honestly I'm in favour of the UK taking a much lesser role in international affairs, as a second rate power we simply shouldn't be rattling around the place like it's the 19th century - We should be more like a Germany or Italy and less like US-lite.
Israel has a few motivations, land is just one of them.
Whether it's land, oil, distracting the plebeians or something else, for the most part it boils down to power.
