Japan's nationalism and rise as an imperial power can be traced backed to what?

The correct answer should be the civil war in which rebels defeated the Tokugawa shogun

Following that war, the Japanese started developing a spirit of Nationalism that caused the death of many.

Freedom of religion, freedom of speech, being protected by our military and first responders on a daily basis and many many more. 

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
