This is your opinion if they we're aggressive. of course When the United States sends a naval delegation, led by Commodore Matthew Perry, to "open" Japanese ports in 1853, the Japanese are well aware of the "Unequal Treaties" that have been imposed upon China in the previous ten years (since the Opium War of 1839-42) as a result of the superior military power of the Western nations. The Japanese respond to the challenge of the West.
So, were they aggressive when it came to their efforts?
