The U.S. Role in the Global ILC Effort

An e+e- Linear Collider in a similar center-of-mass energy range to the LHC was affirmed by the world community in 1999 (HEPAP, ECFA, \& ACFA) as the consensus next global HEP facility. With the ICFA decision in 2004 to adopt a superconducting approach to the RF technology of such a machine the Global Design Effort (GDE) was launched to produce a conceptual reference design and associated cost estimate. This design work also indicated the critical R&D milestones that needed to be demonstrated before the ILC could be credibly proposed to the various funding agencies. This talk will review the global R\&D program and the role of the U.S. within these activities. Recent funding decisions in the U.K. and the U.S. have impacted these efforts and the current status will be outlined. A snapshot of the detector R\&D program will also be given.
