The use of the word "cause" is correct - your understanding of the English language comprehension needs work.
Caused:
1) The producer of an effect, result, or consequence. The one, such as a person, event, or condition, that is responsible for an action or result.
2) A basis for an action or response; a reason.
Destro,
You could use a little work on your people skills. I happen to have a pretty good understanding of the english language and how it is used, and your condescending statement is not appreciated.
Trade sanctions are not an act of war. Countries are free to do business with whomever they please. The refusal to trade with a country does not give them just cause to attack a country.
If Japan invaded Manchuria and did not have their supplies of steel and oil secured, that is not the problem of any other state but Japan. I would like you to explain how it is an act of war.
Furthermore, if you are going to knock someone else's grammar, it is usually a good idea to double-check your own before you do. Your composition could use a little work as well.
I apologize for misconstruing your remarks, I was not giving the subject my full attention at the time. But I disagree with you on the basis of the content of your last post.
