May's deal vs remain are what's on offer
The EU aren't offering anything else
Maybe, but what forces UK to accept the offer? Remember T May saying that no deal is better than a bad deal. EU can't prevent the UK leaving without a deal.
it will be the fault of the brexiters who have trashed it
I will repeat what has been included in my earlier posts;
If people conclude how they voted previously was wrong they can vote differently when the next opportunity to vote comes along. JRM has made that comment on Question Time.
If you no deal, you'll have to go back to the EU and - surprise surprise - they will say, sign the WA and then we'll talk about trade
Can't see EU not wanting to trade with UK in the future. All these threats about WA will soon disappear when there is money to be had. If EU was not bothered about UK leaving they would have said goodbye on 23 June 2016. UK is the third largest donor to the EU.
It has been my view that EU are afraid of the domino effect whereby after one of the members has left others may follow and there will not be an EU. Then to the horror of MEP's they will lose their 100K guaranteed pensions. I remember in the early stages of the settlement negotiations that Brussels talked about the amount needed to guarantee pensions before they started talking about anything else.
