Corbyn wasn't the problem - apart from the fact that he cowed down to the Blairites instead of taking them on over the last 4 years.
He consistently voted on the basis of principle instead of political expediency - something that he should be respected for.
Anti-semitism in the LP was a manufactured scandal - manufactured primarily by the Blairites and the media - a tiny fraction of the LP membership were accused of anti-semitism (less than 0.1% of the membership) and of that number a tiny fraction were shown to stand up to investigation (about 4% of the accusation). The mistake that Corbyn made was not facing down these accusations as politically motivated and without foundation.
At the same time Boris Johnson - who has a record of being anti-Semitic - was allowed to parade around Plymouth praising an anti-Semitic former Tory MP, with the media barely raising an eyebrow. Three Tory candidates were rightly accused of anti-Semitism - none of them were suspended and two of them now sit in the House of Commons. The Tories have a long and very deep history of anti-Semitism, of racism, of sectarianism, of homophobia, of xenophobia - all of which Boris Johnson has openly expressed - yet the entire focus of the media was on a manufactured, fictitious scandal of anti-Semitism in the LP that involved a tiny number of members and which the Blairites used to ensure that Corbyn wouldn't win the election.
I do not agree with Corbyn's position on the North of Ireland - but to suggest he was 'showboating' is nonsense. And Blair did not bring the Troubles to an end - it was primarily political pressure from working class people, Protestant and Catholic, on the republican and loyalist paramilitaries that ended the violence. It is shocking that people think that Tony Blair - a blatant war-monger - had any responsibility for 'peace' in the North. And we do not have 'peace' in the North - we have an absence of violence - none of the problems have been resolved and sectarianism is more deep seated in Northern society now than it was 25 years ago.
Something that people should be conscious of when it talking about the IRA - the IRA's military successes (like the Brighton bomb and the Enniskillen bombing) were their biggest political defeats - and the IRA's military set-backs (like the assassination of 3 IRA members in Gibraltar by the SAS) were their biggest political successes. The political fallout from the Brighton bombing had a major impact on the Republican leadership and was the start of their search for a political solution - I don't know the details of Corbyn's meeting with these minor republican figures and whether it has any impact - but it was the right thing to do. It should also be remembered - that throughout this period the Tory government were in secret talks with the IRA - and that the British state (and the RIC) colluded with Loyalist paramilitaries in the sectarian shooting of Catholics. A friend of mine - and innocent Catholic who just happened to be in the wrong place at the wrong time - was murdered by a Loyalist gunman on 16 July 1986 in North Belfast. The loyalist gunman shot him three times in the back of the head. That loyalist gunman was being handled by the British secret service who were providing him with information - they later shopped him to the IRA after he went rogue and the IRA shot him. Nothing in the North of Ireland is black and white.
Seriously - Corbyn was on a platform with Khaled Mashaal, head of Hamas, in 2012 - Tony Blair met Mashaal in a private meeting and called the the boycott of Hamas after it won the election in 2006 'a mistake'. Corbyn has been accused for calling Hamas 'friends' (he didn't call them that in the context of supporting them) - yet Blairites and Tories alike regularly call the Saudi royal family (the people who have butchered 100,000 people in Yemen) 'friends', 'allies', 'partners' - and never a word about it.
Double standards doesn't even cover it.
Corbyn didn't 'approve' of the mural - he stated that that the mural shouldn't be removed on the grounds of free speech. The artist, LA graffiti artist, Mear One, has repeatedly stated that the mural was not anti-semitic, but anti-capitalist. Critics claimed that the six men depicted were Jewish bankers - the artist outline who the six individuals were - 2 of the six were Jewish. Like the rest of the anti-semitic claims - this is another manufactured scandal.
You have it all wrong - Corbyn has been the victim of a systematic, calculated and sustained smear campaign - initiated by the Blairites, promoted by the media, assisted by the supporters of Zionism and British imperialism and designed to wreck Corbyn's chances of being elected PM. The campaign was so effective that the same forces at play in the USA are attempting to use the same smear campaign against Bernie Sanders - except they have an extra hurdle to jump - Sanders is Jewish.
History and politics are not the same. Politics is the art of the possible. Like football. Sheffield United are demonstrating what is possible. Spurs under Poch at the start of this season were the opposite. I am quite prepared to accept your argument that we got it all wrong about Corbyn. What is missing is the reasons why we (the voters) might consider he had it right (in enough numbers to win). Politics, also, is not about facts, it is about winning.
