No bilateral reset can work without a fundamental shift in tone and approach.
Rather than an over-ambitious treaty however, it might be preferable to opt for a series of bilateral agreements in areas of mutual interest - for example, cooperating in space, building new nuclear reactors to produce green energy and developing joint technologies to protect critical infrastructure, like undersea cables. Regionally, more cooperation in the Sahel and the Middle East seems obvious. The exact form of the agreement will be a matter for discussion. It will also require both sides to chip in ideas - not just the UK.
