Things won't go the way you say it

During the beginning of World war 2, many countries urged the United States to join in the war for the alliances againest the Axis.

However, the never wanted to be involve in the war. The claim they want no involvement in conflict.
Things won't go the way the want it to be. Morning of December 7, 1941, hundreds of Japanese airplanes bombed pearl harbour with the intention to bring America to war. Taking them by surprise, the Americans were unprepared and defenseless againest this attack.

In reality, when you say you don't want to do something, doesn't really means you won't do it. Or you don't want something to happen.

The most probability that things will happen is when you don't expect them to happen. What a wierd world it is.
