- The UKs unique network of diplomatic relationships and influence, often providing access and insight in locations where the USA cannot operate, or where the UK can provide a second voice to influence a nation to support US views.
- The exceptionally close and highly effective relationship between the UK and US intelligence communities, which is of real and genuine value to both nations
- The ability of the UK to offer access to sovereign territory around the world, enabling the US to conduct operations in an extremely permissive environment (and in turn permits the UK a veto over any operations conducted from its territory).
- The provision of certain specialist military assets and capabilities including nuclear weapons, nuclear submarines, Special Forces and ISTAR assets which are on a par with US forces and able to operate in a truly integrated way with them as a 'day one' asset and not as a coalition bolt on at a later date.
All of this combines to ensure that the UK can offer the US a reliable ally who shares their position on many policy issues, and where they can act as a trusted sounding board to provide reassurance and also a second opinion on many matters.
