If say Italy had discovered large amounts of oil in Libya in the 1920s (very hard I know) and started to develop it in the 1930s would the Allies have allowed Italy to become alienated and fall in line with Hitler? Being a strategically important source of oil, or at least future source, would the Allies have worked harder to keep them neutral or just conducted OTL policy and seized the oil fields at first chance when Italy jumps in?
