In the biographies I've read on him, he seems to have been mostly uninterested in affairs outside of Eastern Asia (or at least thought they were less important), which makes sense considering he was in Asia continuously from the 1930s until he was dismissed by Truman. When I say I could see him siding with the UK, France, and Israel, I mostly mean that I don't think he would put too much effort into stopping them. More of a "this isn't a big deal to us so I don't care, im focused on other things" sort of attitude.I don't really see it. Big Mac was big on anti-colonialism, and even criticized Truman for not speeding up decolonization. I just don't see him propping up an invasion of Suez.
