Americans Should Be Blamed For Messing up Diaoyu islands

From the history, we now learnt that the USA has made a big blunder by handing over the Diayu Islands to Japanese after the 2nd world war in the absence of Chiang Kai Sek, the then head of the Republic of China.  Now they pretend to be neutral and would not take any part in the dispute when they can simply admit their mistake and rectify it by returning the islands to China or Taiwan.  I think when the people of the world can force the Japanese to return the islands to China by boycotting Japanese goods, I think it is high time that all Chinese should start to boycott  American goods to force Obama to ratify the mistake.
