'Crash out and pay nothing'. Against this made idea is the argument that we have legal obligations to pay something. Who would want to deal with or trust a nation that failed to meet such obligations? How would paying nothing encourage the EU to trust or trade with us in future?

On the current US administration's dislike of the EU, and its oppositions to standards and regulations, which it likes to see as nothing but barriers to trade (in items such as chlorinated chicken etc), this is well-known. As is US-based support for the right.
