An 'optimistic case' for Remain -- damp squib

An Observer piece has S Khan,Mayor of London, none other calling for a PV and a positive campaign to remain that he calls Project Hope. There is the usual negative start:

The blatant lies, mistruths and deceptions told by the Leave campaign during the EU referendum – which were laid bare for all to see in the Channel 4 drama Brexit: The Uncivil War last week – could not be used again. And those of us arguing to remain could run a campaign full of positivity for the future – Project Hope, not Project Fear....Back in 2016, I – along with Gordon Brown, and others – tried to make this positive, patriotic and values-based case for Britain remaining in the EU, but we were too often drowned out by negative campaigning – on both sides

The positive case turns out to be a rather selective, sentimental and idealised view of recent history:

We can run a campaign highlighting how the EU has been a force for good for generations – boosting our living standards [sic!], strengthening workers’ rights and acting as the greatest movement for peace and democracy the world has ever seen. We can remind people that our connections with Europe are a crucial part of British history – from the Polish Spitfire pilots who fought for our freedoms in the Battle of Britain to the creation of a European union being Winston Churchill’s ultimate dream [Hitler's as well] . We can show people that our own history shows that the benefits of co-operation and being open to the world always eclipse the false comforts of isolation. And we can demonstrate that, when Britain takes a leadership role in Europe, our soft power and influence spreads our liberal democratic values and helps to protect human rights – both of which are more important than ever at a time of rising nationalist populism.

Winston Churchill -- the Labour Mayor's idol. Things like peace and openness equated with membership of the EU. James Bond-like fantasies of leadership based on our British values. Then a bit of optimistic hope for reform, as vague as ever:

in any new vote, we need to show that it’s only through being a proper part of Europe that we can exercise our power and influence on the world stage – allowing us to do more to ensure that all citizens share in the fruits of globalisation and to mitigate some of the consequences of societal and technological changes.

Finally a pretty transparent appeal to the real audience for this stuff:

Lastly, there is one group for whom this decision really matters because it’s their future that’s on the line – young people. Their voice was not properly heard during the 2016 EU referendum and this should not be allowed to happen again in such a crucial democratic decision for the future of our country. One important way to achieve this would be to reduce the voting age to 16...Europe is awash with opportunities for young Britons – whether it’s the chance to go on cultural exchange programmes, study abroad [both a bit dubious if you don't speak another language] or get funding for an apprenticeship [from Europe?]
