"Abandon"
In recent years and under Der Sturmer's government the closest the UK has ever come to recognising a Palestinian state is the cabinet saying that they would acknowledge a two-party state (bingo for outdated bullshit!) but even then ONLY if Israel approved it first. In other words... no reginition, ever, plus just straight up admitting policy is made by Israel.
The UK is starting from the point of being an active and enthisiastic participant in genocide. Not in terms of the shameful political and legal support or interference that would already be a crime. But direct military and financial support. Targeting flights. Intelligence that helps Israel kill journalists and aid workers, some of them British citizens. SAS on the ground. Sheepdipped British forces. We even passed laughably, awfully bullshit arms restrictions and then just lied and broke them anyway. We charge journalists and activists with terror charges, seemingly based on Israel's direction, and then deny their right to fair trial or (few) rights under British law by sharing their information, case progress, and legally protected details with Israel. And that's just the shit that's openly out there, mostly ignored but occassionally acknowledged by mainstream media.
The idea that you can do any of this, never mind all of it, and even pretend to support a Palestinian state is an unhinged fucking lie and everyone telling it in order to distance themselves from the very things they've spent almost two years (or far far more) supporting deserves whatever comes their way and should beg for a jury in the Hague as far more than they deserve.
SciFi with Damien Walters take or whatever is almost as bad, smuglord whether you think Gilroy is hiding his power to skate under Disney's radar or not, the tweet is bullshit liberal grandstanding with zero use or deeper understanding.
