Come on.
The reality is that Johnson achieved very little.
Northern Ireland & the Good Friday Agreement meant there was only two possible ways this could play out.
The first being that the UK stayed in the Single Market and became a rule taker from the EU (making Brexit pointless). The second, a trade border in the Irish Sea.
Theresa May concluded a deal with the EU that kicked the Northern Irish issue down the road but ultimately dealt with the issue by the UK becoming a rule taker. Parliament rejected that.
All Johnson did was pivot to the other option and sell out the Unionists in Northern Ireland. That's literally all he did.
