d)americans could not enforces the un resolution
Answer: B) Saddam Hussein and his regime survived the war.
Your choices included reference to President George H.W. Bush -- whose funeral happened on the morning of the day I'm writing this answer. If the war you are examining was in the time of George H.W. Bush, that means the war against Iraq that you're referencing is the Gulf War of 1991. The United States led a UN coalition of forces to push the forces of Saddam Hussein out of Kuwait after he had invaded that neighboring country. But the US and UN mission limited itself to pushing Hussein's forces back into Iraq, not seeking to remove him from power in Iraq itself at that time.
In 2003, the US again pursued war in Iraq - this time under President George W. Bush (son of George H.W. Bush). The 2003 effort was intended to remove Hussein from power, and did so.
World War I changed the way wars were fought because of the widely known trench warfare. Because troops inside the trenches were much more protected than troops outside, it led to much more prolonged battles.
