Some liquid fueled rockets can be used more-or-less effectively as an ICBM. Despite being extremely volatile, rocket engines powered by hypergolic and room-temperature liquid fuels/oxidizer mixes can be stored fueled in silos for long periods of time. The notable example of this is the Titan II (https://en.wikipedia.org/wiki/LGM-25C_Titan_II https://en.wikipedia.org/wiki/LGM-25C_Titan_II) whiched served as the primary ICBM for the U.S. for 20-odd years (with some mishaps)
