How did the treaties ending World War 1 sow the seeds for future conflict?

Hitler invaded Poland in 1939 which led to the start of World War II.

This was because the treaty conditions for the end of World War I placed some conditions on Germany which they weren’t okay with.

This involved some strict conditions/punishments restrictions imposed on Germany. This led to the payment of a huge war indemnity and occupying of mineral rich areas of the country by France.

This led to Germany subsequently invading Poland to control its resources and recover all what it had lost.

there are isolated pockets of farming, generally around rivers and oases, which are used for irrigation.
