Perhaps (although I disagree) but the point is, when Corbyn says and 'peace and justice', he means it in reference to one kind of person - somebody who has or has been alleged to have attacked Western interests or civilians.
Look at the other examples in the article I linked e.g. the way he described the killing of Bin Laden - a 'tragedy'. To me, a tragedy is when somebody flies an airliner into a building or when a teacher gets beheaded for teaching freedom of expression. But Corbyn didn't say a word about the Samuel Paty beheading (nor did virtually anybody in the Labour Party), and never speaks out about your average non-political miscarriages of justice cases let alone speaks out in cases where British interests have been targeted.
We saw that with the Skripal poisonings. When every other political leader (including Sturgeon) and every other Western country condemned the actions of Russia and Putin, Corbyn's sense of justice went out the window because, for him, peace and justice has always been a one-way street and always will be.
I expect this 'project' will be more of the same and will not bring people together. In fact, the only time Corbyn has brought people together was in 2019 when the country, en masse, voted for the Conservative Party.
