Right now, as events unfold in Gaza, a test case is emerging for British Liberalism, and European Liberalism more broadly, the response to which will say a lot about the state it is in within Western Europe. That test case is the Israeli/Palestinian Conflict.
For too long, some liberals have been indifferent to the persecution of Palestinians by the Israeli state, with the honourable exception of the Liberal Democrats. A lack of forceful criticism or forbidding expression of objection to the actions of the Israeli state, in the case of Emmanuel Macron, is to the disgrace of the noble cause of liberalism. That is why British liberals need to rediscover their liberal heritage to save the reputation of liberalism as something more than what cynics dismiss as mere talk.
