20100903 a question about grammar

Clinton then formally opened the first direct peace talks between Israel and the Palestinians in nearly two years, imploring the two sides to make compromises to forge an agreement.

In a ceremony at the State Department, Clinton said the Obama Administration is committed to reaching a settlement in a year's time. But she stressed that after decades of failed attempts the main work belongs to Israeli PM Netanyahu and Palestinian President Abbas.



不过，我在车上的时候，已经想了一种解释方法，我觉得这样可以讲得通，把那句“肢解”如下：

But she stressed （that [after decades of failed] attempts） the main work belongs to sb.

我后来想了，应该将that作attempts的主语就能说通了，‘[]’号内的为时间状语。

应该不是she stressed that .....
而是she stressed..
然后 that ...attempts....
你觉得呢?

attempts是名词，是可以解释的通的，感觉自己上面分析的是错误的。
