Many times throughout history. Napoleon saw the Poles as a good choice for allies, and France was pushing forward for a strong Poland after WW1.
OK, maybe Poland got a support of France twice but not during the WW2. Maybe they have consequently declared war on Germany, but then just sit and do nothing. If French and British attacked Germany then from the backs, Hitler would be pretty dead around 1940.
And Poland was not THAT mad in 1930s. Maybe this country made some ridiculous decisions but not on such a massive scale as suggested here.
