Re: This is hardly a US speciality...
In addition every one in the leave campaign said a deal would be "easy peasy" to negotiate. Which is why even arch Brexitiers like Gove and Greene have openly admitted that there is no mandate for no deal.
The simple problem with Brexit is that the sort of Brexit that the long term agitators (aka people who never respected the 1975 referendum on membership of Europe) of Brexit want is fundamentally incompatible with the Good Friday Agreement, which basically mandates a customs union and regulatory alignment with the EU.
The deal May has presented (and it's not just her deal it's the EU's too) is as far as you can get from the customs union and regulatory alignment and respect the Good Friday Agreement. Noting there is no electoral mandate for breaking the Good Friday Agreement either.
The simple solution is to ask the people if the deal is acceptable or should we remain. Noting that in 2012 the likes of Mog said a confirmatory referendum on the deal would be perfectly reasonable, and Farage two days before the result said a 52/48 result would be unfinished business and he would not respect it.
