I vaguely remembered a quote about him saying he was impressed with Saddam Hussein's indefatigably.

After going to look it up just there to confirm it was him that said it I saw more of the context around it:

Sir, I salute your courage, your strength, your indefatigability, and I want you to know that we are with you, hatta al-nasr, hatta al-nasr, hatta al-Quds until victory, until victory, until Jerusalem. (https://en.m.wikiquote.org/wiki/George_Galloway)

So whilst I agree that he's out for himself and not someone that I particularly care for, he does seem to have had an interest in that part of the world for the last 30 years or so. This isn't quite the out of the blue political opportunism that some people seem to be suggesting it is.

Is it bad if someone does something good for selfish reasons? Sure it would be nice if everyone was a paragon of virtue but I'd rather have a smarmy prick trying to stop wars because it strokes his ego than a smooth-taking establishment-backer who won't change the status quo in case it hurts the economy.

He claimed that he wears a hat following a hammer attack which left him hospitalised and severely scarred.
