The question needs repeating I am afraid.
''Are you absolutely clear about the consequences that would have on the UK, in 1000s of ways?''
The EU will stick together and supply each other, with the full support of the USA. No Deal would affect them for sure - but it would just DESTROY the uk's businesses, agriculture, fisheries, and have extremely serious consequences for energy supply and prices, medicines, essential chemicals for water purification, and so much more. And of course cause massive problems with NI.
So apart from making you feel better about 'showing them what's what, so there ...' can you give any, any at all, advantages to triggering art 16 and ending up with No Deal.
