1.Now that a man can carry in a bag a bomb that is more powerful than several battleships, it is hard to find out what any country can do or will do next.

【难句解析】now that在这里意为because of the fact that“由于，既然”，引导原因状语。that is more powerful than several battleships为定语从句，修饰bomb。在it is hard to find out what any country can do or will do next中，it为形式主语，不定式短语to find out...next为真正主语。

2.He thought of war simply as an opportunity for cavalry charges and fine uniforms and glory.

【难句解析】Our minister considered war just as charging on horseback and wearing neat uniforms with impressive appearance.
