The Role the United States Played in World War II
As we all know,the second world war was a war of the imperialism.It was substantially the same as the first world war.so the precondion was the same with the united states.
At first,the u s held its neutralism firmly ,as the aggressive behavior of germany didn’t do any harm to it substantively,and it had just experienced the the economic crisis of 1933.what’s more,it could earn a big fortune by selling weapons.The ammunition industry had been developed very well then.And it didn’t waste the advantage and loose the chance.God knows how many inculpable persons were killed by the weapons made by the united states.Maybe we can’t call it slaughter directly,however in some sense,actually it did work a lot.And in the same time,the demand of the ammunition of the world market stimulated the economy a lot.Togethor with the human resources flowing in from urope,american economy developed even in double-digit.surely it was a war profiteer.
But gradually,the economy of america went to saturation.and in the same time,the conflicts in the pacific ocean between the united states and japan became more and more aculeated.So the huge peacefull power joined in and yelled for peace.and soon the second world war finished.of course,the united states’ joining battle worked a lot.but still we can’t say it is for justice and peace only.
In the world war ii,the united state played a complicated role.After it ,also.In urope,the marshall plan was executed.in asia,japan was under controll.The united states became the strongest country undoutedly.
It is a little bit difficult for us to debate wheter the united states played a righeous role or not,as it grasped a big chance to develop itself.
