Well the cause of a certain event in history will mean something happens.
The effect is the result of the event happening
For example. With 9/11 the cause was the twin towers collapsing. The effect would have been thousands of people dying as the result of the planes being highjacked
The U.S and Japan are not in a war, but not at peace either. Japan is damaging the ocean bye whaling (killing whales, no other country in the world does it) over-fishing with mass nets that go for miles, and polluting. The U.S is irritated by this along with several other countries, but have not launched serious ways to stop them as of now.
What war are you talking about ?
<span>Although it is popularly believed that the German army was the first to use gas it was in fact initially deployed by the French. In the first month of the war, August 1914, they fired tear-gas grenades against the Germans. </span>
