The Conquest of Liechtenstein was a long-scale attempt to conquer the microscopically-small country of Liechtenstein. Italy, Switzerland, Austria, and Germany all tried, but in the end experienced epic failure. The conquest is still on-going today and the concept of invading Leichenstein is well-known to be one of the hardest feats that Man has strived to achieve. The concept of invading Leichenstein is so complicated that even the well-known Schlieffen Plan has failed when tasked to invade the country.
