请问高手非限定性定语从句如何再进一步划分句子成分？

North Korea announced Thursday that it will launch its newest rocket, which many outside the country suspect is a long-range missile that can hit the U.S. mainland, sometime from April 4 to 8, giving other countries three weeks to decide whether to shoot it down or deal with the trouble in another way.

想问{which many outside the country suspect is a long-range missile that can hit the U.S. mainland,} 这个定语从句再进一步划分句子成分怎么划？？？？？？？

单看which many outside the country suspect is a long-range missile that can hit the U.S. mainland, 这个句子中的which many outside the country suspect 好像是作主语
而语法上没有查到which加一个句子作主语的用法这里怎么解释？？？？？？

Answer 1

which many outside the country suspect is a long-range missile that can hit the U.S. mainland, 这个句子里面存在2个定语从句。

分析：which many outside the country suspect is a long-range missile 这里是一个定语从句，是以rocket为先行词的。 that can hit the U.S. mainland又是一个定语从句，是以a long-range missile为先行词的。
那么，整句话意思是说，北韩星期四宣布他们会发射一枚最新的火箭，这在外界预测是一枚能够击中美国本土的远程导弹。
我相信你应该知道这句话是什么意思，实际上你看看译文，就知道有2个部分来修饰rocket，就可以得出句中有2个定语从句
