. Britain is the strongest supporter of Israel in the EU and the principle conduit for US insistence on unqualified backing for the Jewish state despite its violations of law and human rights,
What laws and human rights are they violating, and why no ICJ court cases against them? They're the most watched, reported, and observed country in the region, so there should be thousands of cases brought to the ICJ. Why aren't there?
Brexit by itself won't tip the canoe but everything from support for BDS to outright anti-Semitism will get a boost if Britain pulls out and a real jump start if the Union breaks up,
The British press is the most anti-semitic press in Europe, so this is doubtful.
The hang-up is one of legal standing. Israel's alleged crimes are committed against Palestine and Palestine does not have the sovereign status as a UN member to bring a case against Israel before the World Court. This deficiency has been one of the drivers for granting full member status to Palestine and the reason for the frantic US and Israel efforts to prevent it. Step by step, full Palestinian statehood is drawing nearer and with it, the standing to bring suit. Most observers think that the investigations behind the numerous resolutions condemning Israel (resolutions killed by US veto) make the Palestinian suit open-and-shut if it ever gets to court.
The result of a conviction would be sanctions similar to those imposed on Iran or North Korea. This would create insupportable economic pressure on Israel to comply with UN 242. No wonder Likud and the Republican Party are crapping their pants at the very thought.
Your claim that "the British press is the most anti-semitic press in Europe" amazes me. Whatever are you thinking? Do you know anything about the press in Poland, Hungary etc.? Are you confusing anti-Semitism with opposition to Israel government policy? Very strange...
