If I have the honor to be chose to work for the 29th Olympic Games, I will at first improve my English so that I can talk easily about foreign visitors. Second, I will learn more about history of the Olympics as much as the 2008 Olympic Games. Third, since I was familiar with Beijing, I can help visitors find their ways in the city. Finally, I should be able to tell visitors about our history or culture and show them their great achievements. In short, I will do my best to help making the Games a success.

阅读下列材料：

在一次历史课上，同学们谈论了抗日战争胜利的历史意义。

张凯同学说：从鸦片战争以来，中国反抗外国侵略的战争老是失败，像甲午中日战争、八国联军侵华战争……这次，抗日战争可是取得了完全胜利。

周洋同学说：日本不仅侵略中国，还发动太平洋战争，侵略了亚洲许多国家，中国的抗日战争也支援了它们的反侵略战争。

邓迪同学说：抗日战争的胜利来得不容易呀!中国人民付出了巨大的民族牺牲，一共伤亡3500多万人，直接财产损失达1 000亿美元……

请回答：

他们的说法对吗？你认为中国抗日战争的胜利有什么历史意义？
