It makes no sense if you look at it rationally, but wars don't always start rationally.
All the major European powers thought that WWI would be an extremely short affair and that the troops would be home by Christmas.
Hitler thought that the UK and France were not going to honor their guarantee with Poland after hanging out Czechoslovakia to dry.
Imperial Japan thought that they could just sink the US fleet and their vastly economically superior opponent would just give up.
America was literally warned by China that China would join the Korean war if US forces approached the Yalu River and that dipshit MacArthur did it anyway.
Wars aren't rational because people aren't always rational.
