求大佬帮忙分析下该句子成分，。

since military success was thought to result from exceptional personal qualities and could lead to popularity and therefore political opportunity as was the case much later for American presidents Ulysses S. Grant and Dwight D. Eisenhower. 感谢，，

Answer 1

原因状语从句：since military success was thought to result from exceptional personal qualities （分句1-主谓） and could lead to popularity（分句2-主谓宾）
主句（可看作主从复合句）：therefore political opportunity（主句部分省略） as was the case much later for American presidents Ulysses S. Grant and Dwight D. Eisenhower.(定语从句-主系表)

Answer 2

这还不是一个完整的句子，整个结构的意思如下：

• 因为军事上的成功被认为是由于特殊的个人品质，可以带来声望和由此带来的政治机会，就像后来美国总统尤利西斯·S·格兰特和德怀特·D·艾森豪威尔一样。
