WHY NAZİ GERMANY ATTACKED POLAND?

                                            

                Do you know why nazi germany attacked Poland.actually ,there are a lot of cause .ı want to start first cause.nazi germany and soviets unıon agreed.(after germany attacked soviet union).but they hadnt had a border close each other.so they decided to attack to Poland.but ı think this plan creatived by germany.you can ask me”why do you think like this?”.ı am saying quickly.because germany could plan to attack soviet unıon.it is in my opinion.as you can see,hitler is very intelligent.in order that germany wanted to say war is start ,sovıet unıon and germany might attack to Poland.and ı have a another idea.as you can see,hitler was kılled jewry.so in germany some of them had death.so some polish people was soldier.and ı ahve a another idea .in Poland there are a lot of factory.but the factories owners are British.so they could want to have  these factories.but i think  the strenght idea is german’s  soviet union  war preparing.
