There was obviously something going on. I read somewhere that there was an organised social media campaign to get them to the top but that was just a comment on here I think, but also the most plausible reason.
The latest YouGov poll I could find put UK support for Israel at 10% yet somehow they were number one in the public votes. If you mention this in some Israeli discussion board they call you a conspiracist. I guess they’ve got a media machine over there making them think the whole world is behind them.
