A good description of the data in the ISR-Tevatron energy range is found. Predictions for the total, elastic and single diffractive cross sections for the LHC are also presented. The total cross section is expected to be 15% smaller than that given by Donnachie and Landshoff in the model with soft pomeron. The diffractive cross section remains constant in the Tevatron-LHC energy range.6 pages, 3 figures; Talk presented at the XLV Cracow School of Theoretical Physics, Zakopane, Poland, June 3-12, 2005High Energy Physics - Phenomenologytext
