Liz Kendall, the plucky leadership candidate who is trying to reconnect Labour to political reality after five years of Ed Miliband, is right about much that ails her party.
But she's wrong about one thing. Kendall suggested earlier this month that she was the only person bidding to become the next Labour leader who wasn't "continuity Miliband". That, however, can equally be said of Jeremy Corbyn.
Miliband may have inflicted severe damage on Labour's relationship with Britain's Jews, but the hard-left MP would burn the few remaining bridges.
A once-desultory campaign to succeed Miliband has undoubtedly been brought to life by the veteran leftwinger's entry into the race. Expect sparks to fly at next Monday's hustings, organised by Labour Friends of Israel in association with the JC, Jewish Labour Movement and JW3, as Corbyn is questioned about his stance on Israel.
Even those who were strongly critical of Miliband's position on Israel argue that Corbyn's vehement hostility is in an altogether different league.
The former Labour leader, for instance, never showed an ounce of sympathy for Hamas or Hezbollah. Corbyn, by contrast, has said it was his "pleasure" and "honour" to invite "our friends from Hezbollah and our friends from Hamas" to parliament. On Monday evening's Channel 4 News he lost his cool when pushed by Krishnan Guru-Murthy on the matter.
Three years ago, Corbyn emerged as a vocal supporter of Raed Salah, the leader of the northern branch of the Islamic Movement in Israel. Corbyn termed Salah "a very honoured citizen". British judges ruled that Salah had given a sermon invoking the antisemitic blood libel.
A regular at Palestinian Solidarity Campaign events, Corbyn is set to appear next month at an event organised by Middle East Monitor. Among the other speakers, Memo - which the Community Security Trust accuses of peddling conspiracy theories and myths about Jews, Zionists, money and power - has invited is Carlos Latuff, who won second prize in Iran's notorious Holocaust cartoon contest in 2006.
While the Islington North MP may have enlivened the leadership election, many of the Labour MPs who nominated Corbyn simply to allow him on the ballot paper must now be rueing their decision. He had been expected to play the role performed by Diane Abbott in the 2010 leadership election - to articulate the Labour left's old-style socialist message, which could then be decisively rejected.
vCorbyn has, though, defied those predictions - so much so that, in a tight four-way contest, some observers fear he may even top the ballot in the first round of voting and finish second overall.
Under Labour's voting system, a candidate needs 50 per cent of the vote to be elected leader.
While the second preferences of the three other more moderate candidates will ensure that Corbyn is defeated, the long-term impact of such a strong performance by a hard-left can-didate could lead to a further deterioration in Labour's support among Jewish voters.
That Corbyn - in many ways a less attractive and more divisive candidate - looks set to do significantly better than Abbott managed in 2010 is,in part, a reflection of Labour's leftward drift under Miliband as those alienated by New Labour joined or returned to the party.
It is also an unintended consequence of changes to the party rules in 2014 that allow "registered supporters", who are not party members, to vote in leadership elections. Backers of a myriad of minor left-wing parties are said to be signing up as supporters to vote for Corbyn.
Corbyn's presence has already forced frontrunner Andy Burnham to shift to the left. On Israel, the shadow health secretary is, his critics suggest, perhaps closest to a "continuity Miliband" candidate. They fear that while he is backed by strongly pro-Israel MPs such as Rachel Reeves and Michael Dugher, and may recognise the severity of the rift with the community, he will not undertake the "political heavy lifting" required to heal it.
Although her support for Israel is less pronounced than that of her husband, Ed Balls, Yvette Cooper is likely to be better placed than Burnham to build on her already warm relations with the community.
With her determination to break most decisively with the Miliband era, it is, though, Kendall, the only leadership contender not to vote for unilateral recognition of Palestinian statehood in last autumn's vote, who would be most prepared to expend the political capital required to beat back the resurgent, anti-Israel left and reposition her party.
The question for Labour is whether it wants a leader who will do so.
