President Bush's reasons for going to war proved false

Explanation:

The main reason for the invasion of Iraq was the alleged development and usage of bio-chemical weapons by this Middle Eastern country. Representatives from the UN were sent to investigate it, but it turned out that the allegations were false, and that Iraq doesn't develop or have weapons of that type. The UN representatives though were not let to say what they find out and saw, and mysteriously they all died in very controversial accidents in the coming months. Bush's administration though had already set its sights on Iraq and invading it, so despite the allegations being false they attacked it, invaded it, killed their leader, and got hold onto their natural resources.

the catholic church withhold people's access to the bible during the middle ages.

people could go to church and listen to the teachings, but it was absolutely forbidden to own and/or read the books of both the old and new testaments. it was also prohibited to translate the books (which where originally in biblical hebrew) to any other language.

this was done so the church could remain in control of what their teachings were and to enhance their importance and power, while also being able to judge people's actions through information that was unavailable for the general public.
