The European Strategy for Particle Physics is advocating for the construction of an e+e- Higgs factory to address pressing questions in particle physics. The study of the Higgs boson in e+e- reactions is crucial as it may lead to the discovery of new fundamental interactions beyond the Standard Model. The proposed Linear Collider Facility at CERN could offer significant advancements in energy, luminosity, and precision measurements of Higgs couplings. The proposal is ambitious but feasible, with the potential for global support. It emphasizes the importance of precision studies of the Higgs boson and technological innovation for the future of particle physics.
